The correct option is D Genome
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 organisms 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 genomemore than 3 billion DNA base pairs is contained in all cells that have a nucleus.
