Answer 1

Explanation:

The nursing instructor is talking about HIV/AIDS with their pre-nursing pathophysiology class. The instructor explains to the class that the virus that causes HIV/AIDS is called a retrovirus. What characteristics of this retrovirus would the instructor talk with the class about?

a) Transmission of the virus

b) Cure rate of the virus

c) The fact that it is a mutated virus originally thought to be bovine in nature

d) HIV-1 and HIV-2 subtypes

HIV-1 and HIV-2 subtypes

Explanation:

Two HIV subtypes have been identified: HIV-1 and HIV-2. HIV-1 mutates easily and frequently, producing multiple substrains that are identified by letters from A through O. HIV-2 is less transmittable, and the interval between initial infection with HIV-2 and development of AIDS is longer. HIV-1 is more prevalent in the United States and in the rest of the world. Western Africa is the primary site of infection with HIV-2. There is no cure for HIV/AIDS hence, no cure rate. The virus is thought to be a mutation of a simian virus. Transmission of the virus is not a characteristic.

Answer 2

Answer: Retrovirus is a kind of virus that inserts a copy of its genome into the DNA of a host cell that it invades.

Characteristics of retroviruses.

1) It has a single stranded DNA

2) having positive polarity which includes in messenger RNA(mRNA).

3) virus particles, called virions contain two 5′ ("five prime"), end-linked, identical copies of the genome RNA, and therefore said to be diploid.
