Which eukaryotic cell-cycle event is missing in binary fission? (choose the best answer) cytokinesis DNA duplication mitosis cell growth
Answers
The eukaryotic cell-cycle event that is missing in binary fission is mitosis.
Binary fission is a cell division process commonly observed in prokaryotes, such as bacteria.
It involves the replication of the genetic material followed by the division of the cell into two identical daughter cells. However, unlike eukaryotic cells, prokaryotes do not undergo mitosis, which is the process of nuclear division in eukaryotes.
Mitosis is a complex series of events that ensures the accurate distribution of replicated chromosomes into two daughter nuclei. It consists of several phases, including prophase, metaphase, anaphase, and telophase, which result in the formation of two genetically identical daughter cells. Therefore, mitosis is the eukaryotic cell-cycle event that is absent in binary fission.

If a chi-square test for goodness of fit performed with data from a two-factor cross returns a p value < 0.01, ______.
Answers
If a chi-square test for goodness of fit performed with data from a two-factor cross returns a p-value < 0.01, it indicates that there is a significant difference between the observed and expected frequencies.
A two-factor cross refers to an experiment where two factors or variables are studied at the same time.For example, in a genetics experiment, we might study the inheritance of a trait with respect to both the maternal and paternal alleles. A chi-square test for goodness of fit is used to determine whether the observed frequencies of a particular trait or characteristic in the population match the expected frequencies.
If the p-value is less than 0.01, we can reject the null hypothesis, which states that there is no significant difference between the observed and expected frequencies. This means that there is strong evidence to suggest that the two factors being studied are influencing the observed frequencies. The exact interpretation of the results depends on the specific experiment being conducted, but in general, a p-value < 0.01 is considered to be highly significant and suggests that the factors being studied are important in determining the outcome of the experiment.

An enzyme that will digest proteins into amino acids is a protease.
Proteins are large molecules composed of amino acids and are essential for various biological processes. Enzymes are specialized proteins that catalyze specific chemical reactions in the body. Proteases, also known as proteolytic enzymes, are a type of enzyme that breaks down proteins into smaller peptides or amino acids.
Proteases play a crucial role in protein digestion. When we consume dietary proteins, proteases help break them down into smaller peptides or individual amino acids. This breakdown process occurs in different organs, including the stomach, pancreas, and small intestine.
One example of a protease is pepsin, which is produced in the stomach. Pepsin works best in an acidic environment and breaks down proteins into smaller peptides. These smaller peptides are then further broken down into individual amino acids by other proteases, such as trypsin and chymotrypsin, which are produced in the pancreas and act in the small intestine.

(i) Describe the stages that a scientist would complete to obtain this gene.
Answers
Answer: See Below
Explanation:
1. The scientist would need to identify the gene for a protein that would make it glow. For example Aequorea victoria, the jellyfish that produces green fluorescent protein (GFP) is the most common type of fluorescent tag use in biotechnology. This would be done by completing genetic sequencing to identify the gene of interest from the jellyfish cell.
2. The gene could then be amplified through PCR. Assuming this is a bacterial cell, a vector such as pUC19 could be used. The vector and the PCR amplified product would have to be digested. A double digest is recommended to ensure the gene inserts in the proper conformation.
3. Heat shock the plasmid into the cell and proceed on to Blue/White screening to identify which cells contain the gene of interest. You can then isolate and grow the culture containing the GFP gene and induce with IPTG to produce the protein that would make it glow.
Alternatively you could buy a pre-made plasmid from AddGene containing the GFP gene for 75$, complete a miniprep on the cells and heatshock. Either way works.

how do the different phototropic and gravitropic responses make sense from a functional standpoint of the plant organs (i.e. stems, roots, leaves)?
Answers
Phototropic and gravitropic responses in plants play crucial roles in their growth and survival, allowing them to adapt to changing environmental conditions. These responses make sense from a functional standpoint of plant organs as they enable efficient utilization of light and gravity as valuable resources.
Phototropism is the growth or movement of plant organs in response to light. Plant stems exhibit positive phototropism, bending towards the light source, which allows them to maximize light absorption for photosynthesis.
This promotes the growth and development of leaves, enabling them to capture more sunlight. In contrast, roots exhibit negative phototropism, growing away from light sources. This adaptive response helps roots to grow deeper into the soil, facilitating water and nutrient uptake.
Gravitropism, on the other hand, refers to the growth or movement of plant organs in response to gravity. Roots display positive gravitropism, growing downwards towards the gravitational pull. This enables roots to anchor the plant in the soil and explore deeper regions for water and minerals.
Additionally, positive gravitropism in roots ensures that they grow away from the light and towards the darker soil environment. Stems exhibit negative gravitropism, growing upwards against the force of gravity.
This allows stems to elevate leaves and flowers for efficient light exposure, maximizing photosynthesis and reproductive success.
Overall, phototropic and gravitropic responses in plants are adaptive mechanisms that optimize the utilization of light and gravity for the growth and function of different plant organs. These responses ensure efficient energy capture, resource uptake, anchorage, and overall plant fitness in various environments.

the genetic code is: redundant. a quadruplet code. comprised of codons which usually differ at the first position.
Answers
Codons usually differ at the first position, which provides the opportunity for subtle changes in the genetic code to occur.
The process by which data encoded in genetic material (DNA or RNA sequences) is converted into proteins is governed by the genetic code. It is how the body transforms the DNA instructions into the constituent parts of proteins. Codons, which are sequences of three nucleotides, make up the genetic code (the building blocks of DNA). Twenty amino acids can be coded for by each of the 64 available codons.
Due to the redundancy of the genetic code, many codons can encode the same amino acid. Redundancy makes it possible for changes in codon usage to occur without having an effect on the finished protein, providing some evolutionary flexibility. Similar to a quadruplet code, each codon in the genetic code is made up of four nucleotides.

How does having genes on many chromosomes, rather than on just one chromosome, increase genetic variation among offspring?
Answers
Answer:
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. ... A gamete will end up with 23 chromosomes after meiosis, but independent assortment means that each gamete will have 1 of many different combinations of chromosomes
Explanation:
Due to the possibility of genetic material being recombined and shuffled during meiosis, having genes on several chromosomes as opposed to only one chromosome enhances genetic variety among kids.
What is genetic variation among offspring?At locations known as chiasma, the chromosomes overlap. The chromosomes split and reunite at each chiasma, exchanging part of their genes in the process. Genetic diversity comes from this recombination.
The chromosomes align in pairs and cross over during the meiotic process to exchange genetic material. This process results in novel gene pairings on the chromosomes, which can result in the birth of kids with distinctive combinations of features.
Therefore, the possibility of genetic material being recombined and shuffled during meiosis increases genetic variation among offspring.

calculate the fractional saturation for hemoglobin when the partial pressure of oxygen is 44 mm hg . assume hemoglobin is 50 % saturated with oxygen at a partial pressure of 26 mm hg and that the hill coefficient is 3.
Answers
The fractional saturation for hemoglobin is 0.8290 when the partial pressure of oxygen is 44 mm hg.
The fractional saturation for hemoglobin can be described as the ratio of the total hemoglobin which is oxygenated.
The fractional saturation for hemoglobin can be calculated by using the following formula;
FS = (partial pressure of oxygen)^n ÷ (partial pressure of oxygen at which hemoglobin is 50% saturated)^n + (partial pressure of oxygen)^n
Here n represents the hill coefficient
Substituting the values in this formula to determine the fractional saturation;
Fractional saturation = (44)³ / (26)³ + (44)³
Fractional saturation = 85,184 / 17,576 + 85,184
Fractional saturation = 85,184 / 102,760
Fractional saturation = 0.8290
Therefore, the fractional saturation for hemoglobin is calculated to be 0.8290 when the partial pressure of oxygen is 44 mm hg.

Answers
IPSPs (inhibitory postsynaptic potentials) at the postsynaptic neuron have the effect of hyperpolarization, option (b) is correct.
Hyperpolarization refers to a change in the membrane potential of a neuron, making it more negative and further away from the threshold for generating an action potential. When an inhibitory neurotransmitter binds to its receptor on the postsynaptic neuron, it opens ion channels that allow negatively charged ions (such as chloride or potassium) to enter or leave the neuron, depending on the specific receptor and ion channel involved.
This influx or efflux of ions leads to an increase in the negative charge inside the neuron, making it more difficult to reach the threshold for generating an action potential. Therefore, IPSPs have an inhibitory effect on the postsynaptic neuron, reducing its excitability and making it less likely to fire an action potential in response to incoming signals, option (b) is correct.
