Detailed explanation-2: -A genome is the full set of genetic information that an organism carries in its DNA. A study of any genome starts with chromosomes, the bundles of DNA and protein found in the nuclei of eukaryotic cells.

Detailed explanation-3: -A genome is an organism’s complete set of DNA, including all of its genes.
