How does a genomic library differ from a cDNA library?

A) 

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

B) 

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

C) 

The genomic library can be replicated but not transcribed

D) 

A genomic library can be made using a restriction enzyme and

DNA ligase only, whereas a cDNA library requires both of these as well as reverse transcriptase and DNA polymerase

E) 

The genomic library contains only the gene that can expressed in the cell
