Final answer:
An organism's genome can be defined as the complete haploid nuclear DNA content of the organism.
Step-by-step explanation:
The genome of an organism can be defined as the complete haploid nuclear DNA content of the organism. It includes all the genetic material, including gene sequences and other types of DNA. In eukaryotes, the genome consists of several double-stranded linear DNA molecules, which are organized into chromosomes. Each species has a characteristic number of chromosomes, and human body cells have 46 chromosomes.
