A genomic library is a database where the sequence of an organism's genome is stored a collection of many clones possessing different DNA fragments from the same organisms bound to vectors a place where the information of the genetic organization of organisms are kept. a book that describes how to isolate DNA from a particular organism TRUE ANSWER : ? YOUR ANSWER : ?
The advantage of using DNA polymerases from thermophilic organisms in PCR is that the DNA polymerases of these bacteria can withstand the high temperatures needed to denature the DNA strands All of these the DNA polymerases of these bacteria are much faster than those from other organisms the DNA polymerases of these bacteria never make mistakes while replicating DNA TRUE ANSWER : ? YOUR ANSWER : ?
Charged molecules are separated based on varying rates of migration through a solid matrix when subjected to an electric field. This technique is known as autoradiography gel electrophoresis blotting photoreactivation TRUE ANSWER : ? YOUR ANSWER : ?

Bacterial cells protect their own DNA from degradation by restriction endonucleases by not producing any restriction endonucleases methylating the DNA at the sites that the enzyme recognizes deleting all recognition sites from the genome having anti restriction endonucleases TRUE ANSWER : ? YOUR ANSWER : ?
Vectors are molecules that protect host cells from invasion by foreign DNA molecules that degrade nucleic acids molecules that help in replication molecules that are able to covalently bond to and carry foreign DNA into cells TRUE ANSWER : ? YOUR ANSWER : ?
