Question

which of the following statements correctly describes an organisms genome?
a genome is a representation of a single gene locus in an organism.
a genome is a representation of the complete set of polypeptides in any of the organisms cells.
a genome is a complete set of all of an organisms genes.
a genome is made up of the genes found in a gamete produced by the organism.

Explanation:

• A genome is not just a single gene locus (so the first option is wrong).
• It is not about polypeptides (proteins are made from genes, but genome refers to genetic material, not the proteins themselves, so the second option is wrong).
• A gamete has half of the genetic material (in diploid organisms), while a genome is the complete set of an organism's genes. So the fourth option is wrong.
• By definition, a genome is a complete set of all of an organism's genes.

Answer:

A genome is a complete set of all of an organism's genes.
