A genomic library contains all of the genes of a particular organism stored in plasmids or phages. True OR False
Reverse transcriptase transcirbes (makes) RNA from DNA. True OR False
Answer:
1. True
Explanation:
A genomic library is a collection of the total genomic DNA from a single organism. The DNA is stored in a population of identical vectors, each containing a different insert of DNA.
2. False
Explanation:
Reverse transcriptase transcirbes (makes) DNA from RNA.

54. The advantage of a cDNA library of eukaryotic genes compared with a genomic library is that the cDNA library: a. always has the entire gene sequence b. lacks introns C. contains both introns and exons d. consists of single-stranded DNA e consists of RNA and DNA 55. Which of the following is an example of a cloning vector? a. Human growth hormone b. Mosquito c. Plasmid d. Tick e. Ribosomal RNA 56. Transformation in recombinant DNA technology: a. Requires...
(Choose the best answer) A polylinker increases the versatility of a DNA plasmid because it contains: a DNA recognition sequence for several different restriction enzymes. an antibiotic resistance cassette that allows selection in multiple different species. an origin of replication that is not organism-specific. a reverse transcriptase sequence. A BamHI restriction enzyme recognition sequence. cDNA libraries are the same as genomic libraries. include DNA from noncoding sequences. require DNA polymerase for their construction. require reverse transcriptase for their construction. are...
If the two genes are unlinked, an organism with the genotype of AaBb can produce gametes containing either Aa or Bb. AB, Ab, aB, or ab. AaBb. AB or ab. none of the abov Which of the following is NOT correct about miRNA? It is involved with posttranscriptional regulation in eukaryotes. It leads to one type of RNA interference. Its name is derived from “mitochondrial RNA.” It binds to a complementary mRNA sequence. It is found in many different organisms,...
Which enzyme is critical to making a cDNA library but is not used in making a genomic library? O Reverse transcriptase O Restriction enzymes O DNA ligase O Both processes use the same enzymes The number of protein coding genes in the human genome was almost exactly the number that was predicted prior to the human genome project. O True False Multiple bacterial genes under the control of a single regulatory region is an example of O an operon O...

R (resistant) plasmids confer resistance on their parent organism because OR plasmids encode genes that inactivate drugs. OR plasmids encode enzymes that pump out drugs. OR plasmids encode enzymes that prevent drug uptake. OR plasmids only encode genes, not enzymes all of the above O a, b, and c Which of the following is not a resistance mechanism in microorganisms? O alteration of antibiotic to inactive form O modification of antibiotic target O development of resistant...
