Answer: Option A
Solution
Answer: Option A
Solution:
Viruses having Reverse transcriptase enzyme is Retroviruses.The enzyme reverse transcriptase (RT) was discovered in retroviruses almost 50 years ago.
A retrovirus is a type of virus that inserts a DNA copy of its RNA genome into the DNA of a host cell that it invades, thus changing the genome of that cell. After invading a host cell's cytoplasm, the virus uses its reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro.
