Chapter 18, Problem 2CCQ
Summary Introduction
To analyze:
To find the genome in different species.
Introduction:
A genome is defined as a complete set of chromosomes found in an individual. The genome contains complete hereditary information that is encoded in the DNA. In some viruses, genetic information is stored in RNA. For example, humans contain 23 sets of chromosomes, that is, a total of 46 chromosomes are found in a human cell.
