Question

Quizplus · Accepted Answer

The loops of double-stranded DNA formed when eukaryotic DNA is hybridized with mRNA are called introns. In contrast, exons are the coding regions of DNA that are transcribed into mRNA and retroviruses are a type of RNA virus that can convert their RNA genome into DNA and integrate it into the host cell's DNA. Transcripts refer to the product of transcription, which is mRNA. Puffs are visible chromosomal regions in the giant polytene chromosomes found in certain tissues of dipteran insects.
