Chapter 1, Problem 11TYK
Summary Introduction
To review:
Whether the viruses can be considered living, based on their characteristics.
Introduction:
A virus is a small infectious agent composed of DNA/RNA (deoxyribonucleic acid/ribonucleic acid) and a protein coat. Viruses cannot replicate on their own and need the machinery of other cells. Viruses are mostly host specific. They perform the lytic cycle to replicate them and then burst out of the host cell, or may undergo lysogeny.
