Answer:
The term given to DNA and genes together is genome, or genetic information.
Explanation:
The genome comprises the totality of DNA molecules found in the chromosomes of a species, each of these chromosomes containing the genes that determine the synthesis of specific proteins.
Each DNA molecule forms a chromosome, and sections or fragments of this DNA molecule are distributed in the genes of this chromosome. Each gene contains a specific sequence of DNA nucleotides which, translated into the genetic code of RNA, carries the information needed to synthesize proteins that determine the morphology and function of a living being.
