Chapter 17.2, Problem 3SB
Summary Introduction
To review:
The distinctive property of retroviruses among RNA (ribonucleic acid) viruses with respect to the replication of genome.
Introduction:
Viruses are classified on the basis of their genetic material into DNA (deoxyribonucleic acid) and RNA viruses. DNA viruses are those in which the DNA acts as genetic material while RNA viruses have RNA as the genetic material. RNA viruses can either replicate their RNA or convert it into DNA.
