Chapter 19, Problem 4TYK
Summary Introduction
Introduction: Retrovirus is a widespread infectious agent that has been identified in many eukaryotes including humans. Retroviruses are of great importance as they are mostly linked with diseases such as AIDS and cancers. Retroviruses are icosahedral viruses that have an envelope. They have single-stranded RNA as genetic material.
