Which of the following is NOT true regarding the differences between a genomic and cDNA library? Select one: a. A genomic library is prepared from total genomic DNA, whereas a cDNA library is prepared from mRNA. b. Genomic libraries contain much more sequence information and are much larger than cDNA libraries. c. Genomic libraries contain coding and noncoding (regulatory, intron, etc.) sequences, whereas cDNA libraries contain only coding sequences along with their associated 5? and 3? untranslated regions. d. cDNA libraries are generated with the use of reverse transcriptase, whereas genomic libraries are not. e. Genomic libraries contain fewer restriction enzyme sites, whereas cDNA libraries contain many morE.

Kody Callahan · Answer 1

Genomic libraries contain fewer restriction enzyme sites, whereas cDNA libraries contain many more

Explanation:

The comparison between genomic and cDNA libraries is indistinct to the number of restriction-enzyme sites. A genomic library contains a set of DNA clones from an organism, while a cDNA library is composed by DNA fragments which are complementary to the mRNA
