Where is DNA located in a cell?

Back

DNA is primarily found in the nucleus of eukaryotic cells.

Front

Can mutations be inherited?

Back

Yes, mutations can be passed from parents to offspring if they occur in the germ cells.

Front

What is a chromosome?

Back

A chromosome is a long strand of DNA that contains many genes and is found in the nucleus of a cell.

Front

What is the role of DNA in living organisms?

Back

DNA carries the genetic information necessary for the growth, development, and functioning of living organisms.

Front

What is a harmful mutation?

Back

A harmful mutation is a change in the DNA that negatively affects an organism's survival or reproduction.

Front

What is a beneficial mutation?

Back

A beneficial mutation is a change in the DNA that enhances an organism's ability to survive or reproduce.
