Which statement concerning a genomic library is true?
A) It comprises the genomic DNA from an organism.
B) It can be made only for eukaryotic organisms.
C) Every colony in the library has only one gene.
D) It can be made only from cDNA.
E) Reverse transcriptase is essential to construct the library.

Question

Quizplus · Accepted Answer

A genomic library comprises the entire genomic DNA from an organism. This includes both coding and non-coding regions of DNA.

Answer: None of the other choices are true.
 B is incorrect because genomic libraries can be made for both prokaryotic and eukaryotic organisms. C is incorrect because each colony in the library may contain multiple genes or non-coding regions. D is incorrect because cDNA libraries are only made from transcribed mRNA and do not contain non-coding regions or genomic introns. E is incorrect because reverse transcriptase is only used in the construction of cDNA libraries, not genomic libraries.
