The mRNA looks shrunk in front of the length of the DNA that codes for it because post-transcriptional modification eradicates the introns.
As a result, the DNA template releases the RNA molecules created by transcription as single strands. The fact that RNA molecules are significantly shorter than DNA molecules is due to the fact that only a small portion of the DNA is duplicated while making RNA.
A human chromosome's DNA molecule can be up to 250 million nucleotide pairs long; in comparison, the majority of RNA molecules are only a few thousand nucleotides long, and many are even less. The RNA strand loses its hydrogen connection with the DNA template strand, in contrast to a freshly created DNA strand.
The DNA helix reforms and the RNA chain is moved slightly behind the area where the ribonucleotides are being inserted.

Refers to the gene for the ability to taste PTC
Answers
To answer this question, we will make the punnet square. But firts, let us to make the following considerations:
1. The ability to taste PTC is a dominant trait.
Therefore,
2. The genotype of the dominant homozygous is TT and he/she is taster of PTC.
3. The other member of the couple must be homozygous, because she/he expresses the recesive trait. Therefore, the genotype of the latter member of the couple must be tt.
Now, let us draw the punnet square for this situation:
As you can see, in this case all members of the offspring are heterozygous and tasters of PTC.

Which of these meals would give you most of the nutrients that you need ?
1 .Meat, milk and a piece of chocolate
2 .Bread, vegetables and fish
3 .Vegetables, fruits and water
4 .Meat, fish and bread
Answers
Vegetables and fruits are excellent sources of vitamins, minerals, and dietary fiber, while water is essential for hydration. While the other options may contain certain nutrients, they might not provide as balanced and varied a nutrient profile as the combination of vegetables, fruits, and water.
Vegetables and fruits are rich in vitamins A and C, folate, potassium, and dietary fibers, while water keeps the body hydrated. Additionally, a diet rich in vegetables and fruits has been associated with reduced risk of chronic diseases such as heart disease, diabetes, and cancer.
While meat, milk, chocolate, fish, and bread are also important sources of essential nutrients, they do not provide the same variety and amount of nutrients as a diet rich in vegetables, fruits, and water. Furthermore, foods like meat and milk are high in saturated fat and cholesterol, which can contribute to chronic health problems if consumed in excess.

What was the climate like prior to the extinction ?
Answers
Answer:
The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.

Explain the limitation binomial nominclature (15 marks)
Answers
Answer:
- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.
What is binomial nomenclature?
Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.
Binomial Nomenclature also known as the binary nomenclature.
It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.
The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.
Both of this term is written in italic and the genus name is capitalized.
Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.
Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.
These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.
Summary of the limitation binomial nominclature:
- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.
Which of the following is correct with respect to contact transmission? a. Transmission, which occurs through an infected organism biting a potential host, is known as indirect transmission
b. Transmission, which occurs through someone touching a door handle that is a reservoir for an infectious agent is known as direct transmission
c. Transmission, which occurs through a flea carrying an infection from one host to another, is known as vector borne transmission d. Transmission, which occurs through contaminated soil, is known as vector borne transmission
Answers
Answer:
The correct answer is option b: Transmission, which occurs through someone touching a door handle that is a reservoir for an infectious agent is known as direct transmission.
Direct transmission refers to the spread of an infectious agent from one person to another through direct contact, such as touching, kissing, or sexual contact. It can also occur through droplet transmission, such as when an infected person coughs or sneezes and releases respiratory droplets that are then inhaled by others.
Indirect transmission (not option a) occurs when the infectious agent is spread through an intermediate source, such as contaminated objects or surfaces, or through an insect or other animal vector.
Vector-borne transmission (not option d) occurs when an infectious agent is transmitted to humans through the bite of an infected insect or other arthropod, such as a mosquito or tick.
Option c is correct in describing vector-borne transmission.

Makes predictions about future events: Scientific Hypothesis. Based on observations of natural phenomena: Both Scientific Theory and Scientific Hypothesis. A tentative statement used to guide scientific investigations: Scientific Hypothesis. A well-established, highly reliable explanation: Scientific Theory
A scientific hypothesis is a tentative statement or prediction that can be tested through scientific investigation. It is based on observations of natural phenomena and can make predictions about future events.
A scientific theory, on the other hand, is a well-established and highly reliable explanation supported by a substantial body of evidence. It goes beyond individual observations and hypotheses, providing a comprehensive understanding of a particular phenomenon or set of phenomena.
Both scientific theories and hypotheses can be tested by many independent researchers to ensure the validity and reliability of the findings. Therefore, the term "Can be tested by many independent researchers" applies to both scientific theories and scientific hypotheses.
By categorizing the given terms, we can see that "Makes predictions about future events" corresponds to a scientific hypothesis, "Based on observations of natural phenomena" applies to both scientific theories and scientific hypotheses, "A tentative statement used to guide scientific investigations" refers to a scientific hypothesis, "A well-established, highly reliable explanation" represents a scientific theory, and "Can be tested by many independent researchers" applies to both scientific theories and scientific hypotheses.
