What information cannot be determined from the DNA sequence of a cDNA clone?
A)exon sequences
B)sequence of the promoter
C)similarity to previously identified sequences
D)amino acid sequence of the encoded polypeptides
E)sequence of the spliced mRNA transcript

Question

Quizplus · Accepted Answer

The sequence of the promoter cannot be determined from the DNA sequence of a cDNA clone because cDNA is synthesized from mRNA, which does not include promoter regions. Promoters are located upstream of the transcription start site in the genomic DNA, not in the mRNA.
