D) introns.
E) leader sequences.

Question

Quizplus · Accepted Answer

The regions of DNA in a eukaryotic gene that contain noncoding base sequences are called introns. Enhancers are regulatory sequences that increase the transcription of a gene, mRNAs are the messenger RNA molecules that carry the genetic information from DNA to ribosomes for protein synthesis, hnRNAs are heterogeneous nuclear RNAs that are processed to form functional RNA molecules, and leader sequences are regions of DNA or RNA that promote the binding of ribosomes to mRNA molecules.
