Back

DNA replication is the process by which a DNA molecule makes an exact copy of itself, resulting in two DNA molecules, each containing one original strand and one new strand.

Front

What forms the sides (backbone) of the DNA ladder?

Back

The sides of the DNA ladder are formed by deoxyribose (sugar) and phosphate.

Front

What are the four nitrogen bases in DNA?

Back

The four nitrogen bases in DNA are adenine, thymine, cytosine, and guanine.

What is the role of cytosine in DNA?

Back

Cytosine is one of the four nitrogen bases in DNA and pairs with guanine.
