What is a substitution mutation?

Back

A mutation where one nitrogen base is replaced by another in the DNA sequence.

Front

What is an insertion mutation?

Back

A mutation where an extra nitrogen base is added to the DNA sequence.

Front

What is the role of chromosomes in genetics?

Back

Chromosomes carry genetic information in the form of genes.

Front

What is the significance of nitrogen bases in DNA?

Back

Nitrogen bases (A, T, C, G) are the building blocks of DNA and determine genetic information.

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific protein.
