Science Quiz Vocab

the genetic material that carries information about an organism and is passed from parent to offspring. Also known as Deoxyribonucleic Acid.

• DNA

• Gene

• Rungs

• Bonds

The action of copying something; the process by which DNA makes an identical copy of itself.

• Epigenetics

• Genotype

• replication

• backbone

The portion of the DNA double helix that provides structural support to the molecule (comparable to the sides of a ladder); comprised of deoxyribose, sugar, and phosphate.

• rungs

• backbone

• bonds

• gene

Horizontal steps on a ladder; refers to the paired nitrogen bases in a DNA molecule.

• Deoxyribose

• Nitrogen Base

• bonds

• rungs

Active forces that hold a molecule together

• Rungs

• Bonds

• backbone

• double helix

Macromolecules that are made up of long chains of amino acids. These are the building blocks of life with essential structures and functions needed for survival.

• Protein

• phosphate

• deoxyribose

• nitrogen base

Nitrogen bases that consistently pair together. Adenine pairs with Thymine and Guanine pairs with Cytosine.

• Phosphate

• Double Helix

• Nitrogen Base

• Complimentary Base Pairs

The shape of DNA; a twisted ladder

• Complimentary Base Pairs

• Double Helix

• Replication

• Nitrogen Base

They make up the rungs of a DNA molecule. A DNA strand has four bases: Adenine, Thymine, Cytosine, Guanine.

Nitrogen-containing biological compounds that form nucleotides

• Nitrogen Base

• Deoxyribose

• Phosphate

• Bonds

A sugar that alternates with phosphate to form the backbone of the DNA molecule; the nitrogen bases bond to the deoxyribose.

• Deoxyribose

• phosphate

• Nitrogen Base

• Bonds
