B)mRNA
C)exons
D)introns

Question

Quizplus · Accepted Answer

Exons are the fragments of protein-encoding information that make up a human gene. They are the segments of DNA that are transcribed into mRNA and ultimately translated into proteins. Introns, on the other hand, are non-coding segments that are spliced out during RNA processing. While DNA is the genetic material that makes up genes, it is not specifically composed of protein-encoding information. mRNA, meanwhile, serves as an intermediary between DNA and proteins, but is not a component of the gene itself.
