Ordinary cell division produces two daughter cells that are genetically identical. This type of cell division is important for a

Ratling [72]

Answer:

C) production of sperm and eggs

Explanation:

Sperms and eggs are the male and female gametes respectively. Formation of sperms and egg cells require meiotic cell division. Meiosis in sperm mother cells and egg mother cells reduces the chromosome number of half in the sperms and eggs. Meiosis also adds new gene combinations in these gametes by the process of crossing over.

Mitosis cannot reduce the chromosome number to half in the sperms and eggs. Absence of crossing over in mitosis leads to the formation of genetically identical progeny cells from mitosis.

Hence, mitosis can not form sperms and egg cells. If it does, the sperms and egg cells would not have genetic variations and there would be doubling of chromosome number with each round of sexual reproduction.

AZT is a reverse transcriptase inhibitor. How does this drug prevent the replication of a retrovirus

Artemon [7]

Answer:

AZT is a thymidine analog

Explanation:

Azidothymidine (AZT) is an antiviral drug used for the treatment of the Human immunodeficiency virus infection (HIV/AIDS) by preventing the transmission of HIV from infected cells. AZT is capable of suppressing the activity of the enzyme reverse transcriptase of the retroviral HIV genome, which enables it to copy RNA into DNA. In infected cells, this double-stranded DNA is integrated into the host genome which is then instructed to produce identical HIV copies. AZT is a thymidine analog that is incorporated into DNA and thus interferes with DNA synthesis, thereby inhibiting cell proliferation.
