Which of the following sequences would NOT be represented in a cDNA library?
A) promoter sequences
B) translation termination codons
C) polyadenylation signals
D) translation initiation codons

Question

Quizplus · Accepted Answer

A cDNA library is constructed by reverse transcription of mRNA, which only includes sequences that are transcribed from the gene, such as coding regions, untranslated regions, and polyadenylation signals. Promoter sequences are not transcribed from the gene and thus would not be represented in a cDNA library. Translation initiation codons and polyadenylation signals are transcribed from the gene and would be represented in a cDNA library. Translation termination codons are part of the coding region and would also be represented in a cDNA library.
