Define and describe changes in genetic material including mu

Define and describe changes in genetic material, including mutations and mutagens.

What is the importance of genetics, what does it involve and/or include, and why is it important?

Solution

1. Mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level.Mutagens may be of physical, chemical or biological origin. They may act directly on the DNA, causing direct damage to the DNA, and most often result in replication error. Some however may act on the replication mechanism and chromosomal partition..

Physical mutagens

Chemical Mutagen :

A large number of chemicals may interact directly with DNA.

Biological agents

2. Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology.

It includes:

Impotance of genetics:-

The study of genetics is important because it helps scientists identify and understand diseases. By gaining a deeper understanding of the body, scientists can determine how likely members of the population are likely to inherit a disease and help people manage their risks accordingly.
