scoundrel [369]

Answer:

An extracellular molecule activates a membrane protein, which in turn activates molecules inside the cell.

Signal transduction may be defined as the cellular process in which the signal is transmitted into the cells. The signal transduction results in the detection of the stimuli and the effects generated in the body.

The signal transduction initiates the series of cascade for the signal transmission. The protein is activated by the extracellular molecule and activates the different molecules by the phosphorylation at the different steps of the transduction.

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.
