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.
<span>These are explained by (D) punctuated equilibrium. This particular model of evolution is described as a large amount of evolutionary change that occurs in a very short 'punctuated' period of time. Unlike most evolutionary changes, which occur over thousands of years, this model describes evolutionary changes that occur suddenly after a certain event.</span>
