Question

6) How does a genomic library differ from a cDNA library?

A) A genomic library contains coding and noncoding sequences, whereas a cDNA library contains only coding sequences.

B) A genomic library varies, dependent on the cell type used to make it, whereas the content of a cDNA library does not.

C) A genomic library can be made using a restriction enzyme only, whereas a cDNA library requires plasmids and DNA ligase.

D) The genomic library can be replicated but not transcribed.

E) The genomic library contains only the genes that can be expressed in the cell.

Explanation / Answer

A) A genomic library contains coding and noncoding sequences, whereas a cDNA library contains only coding sequences. ---> TRUE

B) A genomic library varies, dependent on the cell type used to make it, whereas the content of a cDNA library does not. -----> FALSE

C) A genomic library can be made using a restriction enzyme only, whereas a cDNA library requires plasmids and DNA ligase -----> FALSE (A genomic library requires restriction enzymes and DNA ligases, while the cDNA library requires both of them and also the reverse transcriptase)

D) The genomic library can be replicated but not transcribed. ---> FALSE (The genomic library can be replicated and transcribed)

E) The genomic library contains only the genes that can be expressed in the cell. -----> FALSE (The genomic library contains both the coding and noncoding sequences)
