The complete set of genetic information in an organism is referred to as what?

The term that describes the complete set of genetic information in an organism is the "genome." The genome encompasses all of the organism's genes, including both coding DNA (which contains the instructions for making proteins) and non-coding DNA (which may have regulatory functions, as well as other roles). It is essentially the entire hereditary information that resides within the chromosomes of the organism and dictates various biological functions and traits.

In contrast, other options represent different, but related concepts. The gene pool refers to the collection of different alleles within a population rather than an individual organism. A chromosome is one structure within the genome that contains genes, but it does not represent the entire set itself. The DNA sequence refers to the specific order of nucleotides within a DNA molecule, while the genome includes all of these sequences organized across all chromosomes in an organism. Thus, the genome is the most comprehensive term for the complete genetic information in an organism.
