in 1964, nirenberg and leder used the triplet binding assay (also known as the ribosome binding assay) to determine specific codon assignments. a complex of which components is used in this type of assay?
Answers
In the triplet binding assay, also known as the ribosome binding assay, a complex of three components is used to determine specific codon assignments. These components include: (i) Ribosomes (ii) Transfer RNA (tRNA) (iii) Messenger RNA (mRNA)
1. Ribosomes: Ribosomes are the cellular organelles responsible for protein synthesis. They consist of large and small subunits composed of ribosomal RNA (rRNA) and proteins. Ribosomes serve as the site of translation, where messenger RNA (mRNA) is read and converted into protein sequences.
2. Transfer RNA (tRNA): tRNA molecules are small RNA molecules that carry amino acids and recognize specific codons on mRNA during translation. Each tRNA molecule is associated with a specific amino acid and contains a three-nucleotide sequence called the anticodon, which is complementary to the codon on the mRNA.
3. Messenger RNA (mRNA): mRNA molecules carry the genetic information from DNA to the ribosomes for protein synthesis. They consist of a sequence of nucleotides that encode the order of amino acids in a protein. Each codon on the mRNA corresponds to a specific amino acid or a stop signal.
In the triplet binding assay, ribosomes are incubated with a mixture of tRNAs and radioactively labeled amino acids. The tRNAs compete with the labeled amino acids to bind to the ribosomes, depending on their anticodon sequence.
By observing the binding of specific tRNAs to ribosomes, Nirenberg and Leder were able to deduce the codon assignments for different amino acids, thereby cracking the genetic code.

Is phospholipid bilayer the same as cell membrane?
Answers
The cell membrane is composed of two layers of phospholipid molecules, but also contains other macromolecules such as membrane proteins, and carbohydrates.
The lipid bilayer (also known as the phospholipid bilayer) is a thin polar membrane composed of two layers of lipid molecules. These membranes are flat sheets that surround all cells in a continuous barrier. Almost all animals and many viruses have lipid bilayer cell membranes, as do the nuclear membrane encircling the cell nucleus and the membranes of the cell's membrane-bound organelles.
The lipid bilayer acts as a barrier, keeping ions, proteins, and other molecules where they are needed and preventing them from diffusing into locations they should not be.

________ convey impulses from lamellated corpuscles and synapse with another neuron in the posterior gray horn of the spinal cord.
Answers
Neurons convey impulses from lamellated corpuscles and synapse with another neuron in the posterior gray horn of the spinal cord.
Lamellated corpuscles are specialized sensory receptors found in the skin that respond to pressure and vibration. When they are stimulated, they generate an electrical impulse that is transmitted along sensory neurons to the spinal cord. The synapse with another neuron in the posterior gray horn of the spinal cord allows for the integration of sensory information and the initiation of a motor response, leading to a coordinated reflex action. This process is part of the somatosensory system, which allows us to perceive and respond to sensations in our environment.

A condition characterized by white, leathery spots inside the mouth; may develop into oral cancer.
a. True
b. False
Answers
The correct option is True. The condition characterized by white, leathery spots inside the mouth which may develop into oral cancer is called leukoplakia. It is a condition that occurs inside the mouth and causes white or gray, thick patches to appear on the gums, tongue, or inside of the cheek.
Leukoplakia is a condition that occurs inside the mouth and causes white or gray, thick patches to appear on the gums, tongue, or inside of the cheek. It's usually painless but can cause discomfort when eating or brushing your teeth.The condition is most common in people who smoke or use tobacco products. However, it may also occur due to other irritants in the mouth such as rough teeth, ill-fitting dentures, or a habit of chewing on the inside of the cheek. Leukoplakia itself is not cancerous. However, some types of leukoplakia may progress to oral cancer over time. If the patches have a rough or raised surface, this may indicate that they are more likely to become cancerous.Treatment of leukoplakia includes removing the source of irritation, such as quitting smoking or fixing an ill-fitting denture. In some cases, the patches may be removed with surgery or laser therapy. It's important to have any suspicious patches evaluated by a dentist or doctor to rule out oral cancer.To learn more about oral cancer Please visit:

why does adding additional substrate overcome competitive but not noncompetitive inhibition?
Answers
Adding additional substrate can overcome competitive inhibition because competitive inhibitors bind to the active site of the enzyme, preventing the substrate from binding.
By increasing the concentration of substrate, the chances of substrate molecules outcompeting the inhibitor for the active site are increased. This allows more substrate molecules to bind to the enzyme and proceed with the catalytic reaction, effectively reducing the inhibitory effect of the competitive inhibitor.
On the other hand, noncompetitive inhibition occurs when the inhibitor binds to a site on the enzyme other than the active site, causing a conformational change in the enzyme's structure. This conformational change can directly inhibit the enzyme's activity by interfering with its catalytic function. In noncompetitive inhibition, adding additional substrate does not overcome the inhibition because the inhibitor is not competing with the substrate for the active site. Instead, the inhibitor affects the enzyme's overall function or ability to catalyze the reaction, and increasing substrate concentration does not reverse this inhibitory effect.

Answer:
C. An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line, unless acted upon by an unbalanced force.
Explanation:
In essence, Newton's first law of motion states that an object at rest won't move unless an outside force causes it to move. Similarly, an object moving at a constant speed will continue moving at that same speed indefinitely, unless an outside force causes it to change speed.
for each species shown, describe how the wings of the optix knockout compares
Answers
The specific consequences of an optix knockout vary between species, but generally lead to alterations in wing coloration, pattern, and other morphological features.
In an optix knockout experiment, the wings of each species exhibit differences compared to the normal wing patterns. The optix gene plays a crucial role in wing coloration and pattern formation in various species. When the gene is disrupted or "knocked out," it results in altered wing patterns that vary depending on the species.
For example, in butterflies like Heliconius erato and Junonia coenia, an optix knockout can lead to a significant reduction in the red coloration on their wings, as the gene is responsible for the production of red pigments. In other species such as the monarch butterfly (Danaus plexippus), the optix knockout may not have a noticeable effect on wing color, but could potentially affect other aspects of wing pattern development.
Overall, the specific consequences of an optix knockout vary between species, but generally lead to alterations in wing coloration, pattern, and other morphological features. This illustrates the importance of the optix gene in determining the appearance and functionality of wings in various species.

b:Suppose instead that = 0.1, what then is ? (2 points)P(+)P(+|T+)
c:Why does change so much between a) and b)? (2 points)P(+|T+)
Answers
In part a, the probability of actually having COVID19 antibodies, P(+), is very low (i.e. 0.01). Thus, even with a high conditional probability of testing positive given that one has the antibodies (i.e. P(T+|+) = 0.96), the probability of testing positive overall (i.e. P(+|T+)) is still relatively low.
However, in part b, the probability of actually having COVID19 antibodies, P(+), is much higher (i.e. 0.1). This means that even though the conditional probability of testing positive given that one has the antibodies (i.e. P(T+|+) = 0.96) is the same as before
the probability of testing positive overall (i.e. P(+|T+)) is much higher because there are more people who actually have the antibodies. Therefore, the change in P(+|T+) between a) and b) is due to the change in the prior probability P(+), which affects the denominator of the formula for P(+|T+).

.The highest fertility rates are among each of the following, EXCEPT:a. in locations with strong religious and cultural ethic of large familiesb. in rural areasc. in places with traditional gender rolesd. in heavily industrialized regions
Answers
Fertility rates are not usually high in heavily industrialized regions. The correct answer is option d.
The highest fertility rates are usually found in places with strong religious and cultural ethics of large families, rural areas, and places with traditional gender roles. In these locations, having many children is often considered a cultural norm or social expectation.
However, heavily industrialized regions tend to have lower fertility rates. This may be because of factors such as urbanization, a shift towards more modern family values, and access to birth control and family planning services. Additionally, in many industrialized countries, women have more opportunities for education and career advancement, which can lead to delayed childbearing.

Summarize the order of events from egg and sperm to embryo?
(ill give brainliest)
Answers
Sperm fertilizes the egg, the egg turns into a zygote, the zygote then goes through the process of cell division and turns into an embryo.
• Post ejaculation, the sperm cells meet the egg, and fusion between both the cells takes place.
• The fusion results in the formation of a single cell, which comprises the genetic material from both the egg cell and the sperm cell, this is called a zygote.
• The zygote further divides into sixteen cells stage called the morula.
• Post three days after the formation of morula, formation of the embryo takes place. The embryo attaches to the wall of the mother's uterus.
Thus, egg and sperm fuse and give rise to the zygote, this zygote further undergoes several divisions and eventually results in the formation of an embryo.

The three categories of neurons are called neurons, neurons, and interneurons.a. Trueb. False
Answers
The given statement "The three categories of neurons are called neurons, neurons, and interneurons" is B. False because The three categories of neurons are called sensory neurons, motor neurons, and interneurons.
Sensory neurons are responsible for transmitting sensory information from the body's tissues and organs to the brain and spinal cord. Motor neurons, on the other hand, are responsible for transmitting signals from the brain and spinal cord to the muscles and glands in the body, allowing for movement and other bodily functions. Finally, interneurons are responsible for connecting sensory and motor neurons, allowing for communication and coordination between the two.
It is important to note that these three categories are not mutually exclusive, as some neurons can have characteristics of multiple categories. For example, some sensory neurons can also act as interneurons, transmitting signals between different sensory neurons or between sensory and motor neurons. Similarly, some motor neurons can also receive sensory input, allowing for fine control of movement.
In summary, the three categories of neurons are called sensory neurons, motor neurons, and interneurons, and they play important roles in allowing for communication and coordination within the nervous system. Therefore the correct option is B
