Front

What type of bond joins the two strands of nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

What are the building blocks of DNA?

Back

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

Front

Name the four nitrogenous bases found in DNA.

Back

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

Front

What base pairs with Adenine in DNA?

Back

Thymine (T) pairs with Adenine (A).

Front

What is the role of DNA in cells?

Back

DNA stores genetic information and provides instructions for protein synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.
