Chapter 15, Problem 12TYK
Summary Introduction
Introduction: Chromosomes are the large molecules of genes or DNA. The necessary information for every character of an organism is contained in the DNA. Combinations of thousands of theses genetic molecules control the traits of an organism. During cell division, every DNA molecule synthesizes the exact copies of it, and hence information is passed further to daughter cells.
