Genetic sequence

A genetic sequence (pronounced: jəˈnɛtɪk ˈsiːkwəns) is a term used in the field of genetics to describe the order of nucleotides found in DNA or RNA molecules.

Etymology

The term "genetic sequence" is derived from the English words "genetic", meaning related to genes or heredity, and "sequence", meaning a particular order in which related things follow each other.

Definition

A genetic sequence is a series of nucleotides in DNA or RNA that determines the specific genetic instructions in the process of protein synthesis. Each genetic sequence is unique to an individual organism and is passed down from parents to offspring during the process of reproduction.
