Summary Introduction

To determine:

The semiconservative model of DNA.

Introduction:

Semiconservative replication: It is a description of DNA replication, in which one strand of the DNA act as a template strand for the formation of the other strand. One strand of parent DNA remains unchanged in the daughter strands; hence, it is called semiconservative.

Explanation of Solution

Given below is description of the semiconservative DNA:

Model	During replication, parental DNA strands	The new molecule of DNA is composed of
Semiconservative replication	The parental DNA strands unwind and gives a template for the new daughter stand to form.	The new DNA strand is composed of new nucleotides, which is synthesized by the resources present in the medium.
