DNA, Genes, and Chromosomes

The two nitrogenous bases that are joined by a hydrogen bond and create a "rung" on the DNA ladder.

• gene

• base pair

• nucleotide

• nucleotide sequence

A single strand of DNA tightly coiled around special proteins.

• gene

• nucleotide

• chromosome

• nitrogenous base

The two scientists who discovered the structure and shape of DNA.

• Hooke, Watson

• Crick, Virchow

• Schleiden, Hooke

• Watson, Crick

A long molecule in the shape of a double helix and made up of nucleotides; contains genetic information.

• Deoxyribonucleic acid (DNA)

• ribonucleic acid (RNA)
