Accurately 2 different ways that antiretroviral drugs can prevent virus formation
Nataliya [291]

Answer:

Two different ways in which antiretroviral drugs can prevent the formation of new viruses are:

  1. Inhibiting the reverse transcriptase enzyme in both nucleoside analogues and non-nucleoside analogues.
  2. Enzymatic inhibition of integrase enzymes.

Explanation:

Antiretroviral drugs are those used for the treatment of human immunodeficiency virus (HIV) infection, making the effect of the virus on the host cell is less and preventing the development of AIDS.

This type of drug has been classified, according to their mechanism of action, being grouped into several families of drugs. Two different ways by which antiretroviral drugs can prevent the formation of virus are:

  1. <em><u>Inhibition of reverse transcriptase enzyme</u></em><em>: this enzyme is a DNA polymerase capable of forming single strand viral RNA by a process that is reverse to normal DNA to RNA transcription. Its inhibition prevents the formation of viral particles in the host cell. They are divided into nucleoside analogs and non-nucleoside analogs.</em>
  2. <em><u>Enzymatic Inhibition of Integrase enzymes</u></em><em>: this type of enzyme is contained in the virus, and is capable of causing a retrotranscribed DNA to integrate into the host cell's DNA so that viral replication occurs. Its inhibition prevents the replication process.</em>

The most effective treatments against HIV infection involve the use of two or more types of antiretroviral drugs.

I believe the answer to this question is C or "Always share personal information online".

Explanation:

The reason for this is because the rest make sense to protecting your information. The third answer sounds a little off. This is because you are giving your information to strangers which can cause hackers to get into your accounts. This is why it is not a tip for internet safety.

Hope this helps! Have great rest of your day!
