D) sRNA
E) pRNA

Question

Quizplus · Accepted Answer

mRNA (messenger RNA) is the RNA molecule that serves as an intermediate between DNA and polypeptides during protein synthesis. It carries the genetic information from DNA in the nucleus to the ribosomes in the cytoplasm, where the information is used for protein synthesis. tRNA (transfer RNA) brings amino acids to the ribosomes, rRNA (ribosomal RNA) is a component of the ribosomes, sRNA (small RNA) is involved in regulating gene expression, and pRNA (packaging RNA) is a type of RNA found in viruses.
