Why must DNA be replicated?

Short Answer

Expert verified
DNA must be replicated to ensure that each new cell has an exact copy of the genetic information present in the parent cell. This allows the organism to grow, develop, and function properly.

Step by step solution

01

What is DNA?

DNA, or deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria. DNA is in each cell in the organism and tells cells what proteins to make.
02

Understanding Cell Division

Most of the life of a cell is spent in a period of growth called interphase. Interphase is when a cell makes a copy of its DNA. Cell division occurs in a series of stages, prophase, metaphase, anaphase, telophase and cytokinesis. Before the cell divides hence, all the DNA must be replicated.
03

Reason for DNA Replication

Genetic information must be passed on to new cells during cell division. To achieve this, the DNA in the parent cell must be replicated to ensure the daughter cells have the exact same genetic information as their parent cell. Without this replication process, new cells would have insufficient genetic information to function.
