Frequently Asked Questions

Why is genetics important to study?

Genetics is important because it deals with the study of heredity and the variation of organisms. Genetics affects many different aspects of our lives, from the food we eat to the diseases we get.

By studying genetics, we can learn more about how our genes affect our health and the health of our families. We can also use genetics to improve crops and livestock and develop new treatments for diseases.

What is the difference between genes and DNA?

Genes are the basic unit of heredity. They consist of DNA and are passed on from one generation to the next. Genes control how cell functions and determine what characteristics are passed from parents to their children.

DNA is the molecule that makes up genes. It consists of two strands that wrap around each other like a ladder. The rungs of the ladder are made up of chemicals called nucleotides.


There’s a lot to learn about genetics, but it’s definitely a fascinating area of science with many practical applications. If you want to learn more about genetics, these questions are a good starting point for your journey of discovery.
