Homework Answers
It will require both reverse transcriptase as well as integrarse enzyme for entry in host cell. So last one is correct answer .
Retrovirus have RNA genome which are converted into DNA with the help of reverse transcriptase enzyme. And get integrated into host genome by integrarse enzyme.

IVIUIUalls UOLWOOH Palil alu Udulerd QUESTION 15 2 points Save Answer HIV's genome of RNA includes the code for reverse transcriptase (RT), an enzyme that acts early in infection to synthesize a DNA genome off of an RNA template. The HIV genome also codes for protease (PR), an enzyme that acts later in infection by cutting long viral polyproteins into smaller, functional proteins. Both RT and PR represent potential targets for antiretroviral drugs. Drugs called nucleoside analogs (NA) act against...

COVID 19 is a positive sense single stranded RNA virus. Which of the following is the case, given this information? It integrates its RNA into a host cell this group of viruses is not generally known to infect humans It requires viral reverse transcriptase to convert its genome into a positive sense RNA strand it has a double stranded genome the genome does not need to be transcribed in order for viral proteins to be produced
