Answer:
the answer is B
Explanation:
Option B is not part of the cell theory.
The correct answer is: A. minus end; dynein
Microtubules are cytoskeletal fibers that have an important role in the intracellular transport (movement of vesicles within the cell) and in the mitotic spindle during mitosis. The plus end of the microtubules extend through the periphery of the cells while the minus ends are anchored within the centrosome.
Necessary proteins for the vesicle’s movement are motor proteins:
• kinesin which is positive end directed
• dynein which is negative end directed
So, beside vesicles these proteins are also involved in organelles’ transport in opposite directions through the cytoplasm.
Preventing reverse transcriptase activity is a tactic in the fight against contagious infections like HIV. Drugs can be created that specifically target and inhibit the reverse transcriptase enzyme, essentially freeing your DNA polymerase to carry out its function.

What are reverse transcriptase?</h3>
AZT and DDI are two of the more well-known medications among them. AZT stands for azidothymidine in the acronym. This medication traps the invasive reverse transcriptases and causes them to stop copying RNA into DNA. When that occurs, the HIV virus is unable to multiply, and your immune system can more readily get rid of these infections from your body. Because it is so specialized in combating reverse transcriptase, AZT has been referred to as a magic bullet.
The fact that your body periodically uses reverse transcriptase-like processes for normal functioning makes it far from perfect, and the fact that HIV can swiftly adapt so that it is no longer deceived by AZT make it less than ideal. Because of this, a combination of many reverse transcriptase inhibitors, such as AZT and DDI, is frequently required for an effective HIV treatment.
