3TC is an antiretroviral treatment used to prevent HIV infection from becoming AIDS. After treatment with 3TC, the HIV populatio

n in a patient consists entirely of 3TC-resistant virus particles. What best explain this phenomenon? A) HIV can change its surface proteins through mutations and resist vaccines. B) The patient became re-infected with 3TC-resistant viruses after the initial exposure. C) The drug caused RNA changes to occur, creating a resistance to the once-applicable drug. D) A few drug-resistant viruses were present at the start of treatment and selective pressures increased their frequency.

Use a punnett square to explain how a dominant allele masks the presence of a recessive allele
andrew11 [14]
In this example I used blue and brown eyes. Brown eyes are a dominant trait and are represented by a big B while blue eyes are recessive and represented by a little b. If an offspring gets a B from the father and a b from the mother the offspring will have brown eyes.

Hope this helps!!

The nucleoside analogue acyclovir, which is used to treat herpes simplex virus (HSV) infections, lacks a 3′ hydroxyl group (–OH)
Dima020 [189]

Answer:

There won't be any functional viral DNA synthesis

Explanation:

First of all, you must consider that the HSV has a double-stranded, linear DNA genome. Furthermore, the DNA skeleton is made of the 5'-3' phosphodiester bond. In other words, the 5-phosphat of a nucleotide will bond the 3' OH of the Deoxyribose (see image).

Therefore, if you add a molecule which lacks the 3' OH, such as acyclovir, and has a similar chemical structure to a regular nucleotide, the DNA polimerase will be able to add acyclovir to the main backbone of the viral genome. All in all, you'd be ''cheating'' the DNA pol.

Hence, wherever acyclovir was integrated, there won't be any chance to form a 5'-3' phosphodiester bond. The protomolecule will not be stable and will soon be degradated.
