A complementary DNA library (cDNA) and a genomic library are similar in that both: a. use bacteria to make eukaryotic proteins. b. provide information on whether genes are active. c. contain all of the DNA of an organism cut into pieces. d. clone mRNA. e. depend on cloning in a living cell to produce multiple copies of the DNA of interest.

Which of the following is NOT true of genomic and cDNA libraries? Genomic libraries contain fragments of genomic DNA and contain clones that represent the entire genome. cDNA libraries are made using mRNA. cDNA libraries do not contain introns, while genomic libraries do contain introns. DNA in represented in genomic libraries contain control sequences that direct transcription. Genomic libraries usually contain large fragments and are made using YAC or BAC vectors. All of the answers are true.
