There are choices for this question namely:
<span>a. Human immunodeficiency virus (HIV)
b. T-lymphocyte virus type I
c. Epstein-Barr virus
d. Parvovirus
e. Poxvirus
</span>
The correct answers are HIV, T-lymphocyte virus type I, and Epstein-Barr virus. HIV or human immunodefiency virus will predispose the patient in developing Kaposi sarcoma in later stages of acquired immunodeficiency syndrome. T-lymphocyte virus type I is believed to be the etiological agent for developing T-cell leukemia or lymphoma. Epstein-Barr virus is associated with both nasopharyngeal carcinoma and Burkitt lymphoma.
<em>Parvovirus B19 causes a viral exanthem called erythema infectiosum which has no propensity to malignancy. Poxvirus is the etiologic agent for molluscum contagiosum, also with no propensity in developing malignancy. </em>
Answer: Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

Unify means to make or become united uniform, or whole.
(I personally don't agree that evolution is true; but here is my answer)
Evolution is a way Scientists like to theorize the world was made/ created. They try to explain why everything can about in a uniform way. Everything has a reason or theory. Even though scientists haven't been able to prove that Evolution actually exists, many people like the idea of it- just for the reason that it gives a more believable whole approach to how the Earth and Universe came about. For some people, it is more uniform than a religion.
I hope this helped you!
Answer/Explanation:
DNA polymerase is the enzyme responsible for replicating DNA. It is hugely important that is performs its functions accurately, as if incorrect bases are incorporated this can lead to mutations that disrupt the structure and function of genes. It adds nucleotides in a 5' - 3' direction only.
DNA polymerase III also has high processivity, which means that for every time it binds DNA, it is able to add many bases before it becomes dissociated.
A. DNA polymerase avoids the incorporation of improperly paired nucleotides in two ways:
- The first way depends on the structure of the enzyme. If the nucleotide that the enzyme is in the process of adding is not complementary to the template, then the nucleotide will not align with the template, and thus it is more inefficient to add. This inefficiency means the nucleotide is more likely to leave the active site before it is added, and DNA polymerase can replace it with the correct nucleotide.
- It also has proofreading capabilities. This means, when an incorrect base is added, it recognises the error and can fix this. It can do this because it possesses 3'-5' exonuclease activity. That means, it can chop out incorrectly added bases.
B. Ribonucleotides are the nucleotides that are incorporated into a growing RNA molecule. They are different from deoxyribonucleotides because of the differences in the sugar backbone (ribose vs deoxyribose). Their incorporation would disrupt the structure and function of the DNA, leading to problems with transcription and replication.
DNA polymerase avoids incorporating these nucleotides primarily because of the structure of the enzyme. Ribonucleotides cannot fit into the active site of DNA polymerase due to what is called a "steric filter" or "steric gate". This gate/filter function is performed by specific amino acid residues which usually have a bulky side chain and thus block the incorporation of the 2'OH of the ribose sugar (which is lacking in the deoxyribose sugar)
