An example of a nontranscribed DNA sequence in human DNA is
A) an intron in a beta globin gene.
B) a promoter site for RNA polymerase II.
C) the termination codon for beta globin.
D) the region in ribosomal RNA genes between the segments coding for the l8S and 28S rRNAs.
E) the consensus sequence of exon-intron junctions.

Question

Quizplus · Accepted Answer

Promoter sites for RNA polymerase II are sequences in DNA that are crucial for initiating the transcription process but are not themselves transcribed into RNA. They serve as binding sites for RNA polymerase and other transcription factors, thereby regulating the transcription of adjacent genes.
