DNA Nucleotides

The sugar found in DNA.

• phosphate

• cytosine

• deoxyribose

• dextrose

The base that pairs with cytosine.

• guanine

• thymine

• phosphate

• adenine

Nucleotides are made of a molecule of deoxyribose, connected to a phosphate & a nitrogen base. They make up one side of the DNA double helix.

• true

• false

This part of the nucleotide helps hold the DNA structure together.

• base
