Question

What is a genome?

• A. Part of chromosome.
• B. Half chromosome.
• C. Total DNA in cell.
• D. A complete set of chromosomes.

Answer 1

The correct option is D. Total DNA in the cell.
The genome is the genetic material of an organism. It is encoded either in DNA or, for RNA viruses, in RNA. The genome includes both the genes and the non-coding sequences of the DNA or RNA. A genome is an organism's complete set of DNA, including all of its genes. Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome of more than 3 billion DNA base pairs is contained in all cells that have a nucleus.
