Final answer:
The genome is the entire genetic complement (DNA) of an organism, containing all the hereditary information encoded in the DNA, including genes and non-coding sequences. It is the set of genetic material in an organism's chromosomes.
Step-by-step explanation:
The genome is the set of genetic material in an organism's chromosomes. It is the entire genetic complement (DNA) of an organism, containing all the hereditary information encoded in the DNA, including genes and non-coding sequences. Each human body cell has a full complement of DNA stored in 23 pairs of chromosomes, one set from each biological parent. Genes, the functional units of chromosomes, determine specific characteristics and are responsible for an individual's genotype, while the expression of these genes as physical, behavioral, or biochemical traits is the individual's phenotype.
