Front

What does DNA stand for?

Back

Deoxyribonucleic acid.

Front

What is the primary function of DNA?

Back

DNA holds the code for protein.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogen bases found in DNA?

Back

Adenine, thymine, cytosine, and guanine.

Front

What is the role of adenine in DNA?

Back

Adenine is one of the four nitrogenous bases that pair with thymine in the DNA structure.

Front

What is the role of thymine in DNA?

Back

Thymine is a nitrogenous base that pairs with adenine in the DNA structure.

Front

What is the role of cytosine in DNA?

Back

Cytosine is a nitrogenous base that pairs with guanine in the DNA structure.

Front

What is the role of guanine in DNA?

Back

Guanine is a nitrogenous base that pairs with cytosine in the DNA structure.

Front

What is the structure of DNA commonly described as?

Back

A double helix.
