Question

Quizplus · Accepted Answer

The regions of DNA in a eukaryotic gene that contain noncoding base sequences are called introns. Enhancers are DNA sequences that increase the transcription of a gene. mRNAs are the final product of gene expression and are made up of coding sequences (exons) and noncoding sequences (UTRs). hnRNAs (heterogeneous nuclear RNAs) are precursors to mRNA and are found in the nucleus. Leader sequences refer to the noncoding sequence at the 5' end of an mRNA molecule that is important for translation initiation.
