Chapter 11, Problem 8TY
Summary Introduction
Introduction: There are a variety of living organisms that are present in the environment. Most of the organism contains a nucleus in which the genetic material is stored. The genetic material plays a very crucial role in the functions of the organism. A chromosome is a part of genetic material that contains genes. It is present in the nucleus.

Which of the following statements accurately describes the process of DNA
replication?
