What is the genome?

The genome refers to the complete set of genetic material present within an organism, which includes all of its genes and non-coding sequences of DNA. It constitutes the total genetic information inherited from both parents, encompassing the instructions necessary for the development, functioning, and reproduction of that organism. This set of instructions is organized and stored in the DNA contained within the chromosomes.

While a collection of chromosomes is an important aspect of the genome as it contains the genes, the term "genome" specifically highlights the entirety of genetic information available, rather than just the physical structure of chromosomes alone. Additionally, the total mass of proteins in the body and the total number of genes are related to the functioning and representation of genetic information but do not encompass the complete range of genetic instructions, which is why they do not accurately define the genome.
