The answer is D.
A retrovirus is any of a group of viruses that characteristically carry their genetic information in form of RNA. These viruses have an enzyme called reverse transcriptase from which they derive their name because they follow the first step of the central dogma backward thus "retro" which means backward.
Reverse transcriptase makes DNA from RNA template thus reversing the usual pattern of transcribing RNA using DNA as the template.
The central dogma of molecular genetics summarizes steps of protein synthesis as DNA → RNA → protein. But retroviruses have modified the process to be RNA → DNA → RNA → protein.
Answer:

Answer:
Sharp-spined cactus
Explanation:
Given, that N allele is required for the production of spine and S allele will produce sharp sines.
True breeding sharp spined cactus: NNSS
spineless cactus: nn__ ( we can't fix the allele for second gene since it has not been mentioned as true breeding )
Their progeny: NNSS X nn__ = NnS_
So the progeny is going to be sharp spined because both the dominant alleles N and S are present.
Answer:
