Chapter 25.4, Problem 1R

Summary Introduction

To review:

The effect of the size of the viral genomes on the phylogenetic analyses of viruses.

Introduction:

Viruses are nonliving when present outside the host and perform living organism functions as soon as they come into contact with the host cell or tissue. They play an important role in several areas but their proper habitat and evolution are still not clear. The diseases caused by viruses are very difficult to treat due to their constantly mutating genome.
