DNA Structure and Function

Front

Deoxyribonucleic Acid: a macromolecule that is responsible for storing and passing on genetic information.

Back

DNA

Front

The twisted ladder shape of a DNA molecule.

Back

Double Helix

Front

The monomers of DNA polymers that consist of a phosphate-sugar backbone and a single nitrogenous base.

Back

Nucleotides

Front

Nucleotides pair up to form the rungs of a ladder, and the phosphate-sugar backbone acts like the sides of a ladder.

DNA Structure

Front

What are the 4 possible Nitrogenous Bases in a DNA nucleotide?

Back

Nitrogenous Bases

Front

In DNA, Adenine always pairs with Thymine A-T (Like Apples-Trees), while Cytosine always pairs with Guanine C-G (Like Cars-Garage).

Back

Base Pairing

Front

The weak connection that holds together matching nitrogenous bases.

Back

Hydrogen Bond

Front

The 4 nitrogenous bases, A, T, C, G, are arranged in patterns that become the instructions for building all parts of living things.

Back

Genetic Code

Front

The physical attributes of any living thing that come from the genetic code.

Back

Genetic Traits

Front

Coils formed by the thin double helix strands of DNA, held in place by special proteins called histones to enable safe storage.

Chromosomes
