Unit One: Structure and Function

Front

DNA (deoxyribonucleic acid)

Back

The molecule that carries the genetic information used in growth, development, functioning, and reproduction of all known living organisms.

Front

Protein

Back

Large, complex molecules that are required for the structure, function, and regulation of the body's tissues and organs.

Front

Amino Acid

Back

Organic compounds that combine to form proteins.

Front

Gene

Back

A segment of DNA that codes for a specific trait.

Front

Genotype

Back

The genetic makeup of an individual, with reference to a single trait.

Front

Phenotype

Back

The observable characteristics or traits of an organism resulting from the interaction of its genotype with the environment.

Front

Chromosome

Back

A structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

Front

Ribosome

Back

One of the tiny structures in a cell that is the site of protein production.

Front

RNA (Ribonucleic Acid)

Back

A nucleic acid involved in protein synthesis, acting as a messenger to carry genetic instructions from DNA to the ribosomes where proteins are produced.

Front

Transcription

Back

The process of copying a segment of DNA into RNA.
