Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries genetic information.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the base pairing rule in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Front

What is a gene?

Back

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