Accepted Answer

A gene is a part of DNA that contains instructions to make something important, like a protein in your body. It's like a recipe in a cookbook.

Question 12

How do scientists study DNA?

Accepted Answer

Scientists study DNA by using special machines to read its instructions. They can then learn about how our bodies work and what makes us unique.

Question 13

Why do we need DNA testing?

Accepted Answer

DNA testing can help us learn about our family history or find out if we have any diseases. It can also help solve mysteries in police work.

Question 14
