Answer:
Two different ways in which antiretroviral drugs can prevent the formation of new viruses are:
- Inhibiting the reverse transcriptase enzyme in both nucleoside analogues and non-nucleoside analogues.
- 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:
- <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>
- <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.
Heath Risks
While some side effects of steroids may be just a nuisance, others may be life-threatening. For example, using steroids has been associated with:
Liver problems
Heart problems
Stroke
Blood clots
Cancer
Physical Side Effects
Common physical side effects of steroid use include:
Acne or pimples
Scars or stretch marks
Premature hair loss in males
Deepened voice in females
Excessive growth of body and facial hair in females
Mental Side Effects
Steroid users may become overly aggressive or combative, a condition commonly referred to as “’roid rage.” Uncontrolled aggression causes some steroid users to become confrontational with friends and family; sometimes, they end up in trouble with the law.
