Genes of interest can be selected from a genomic library by using:

Options

  1. Acloning vectors
  2. BDNA probes
  3. Cgene targets
  4. Drestriction enzymes.

Correct answer

B. DNA probes

Step-by-step solution

Gene bank or genomic library is a complete collection of cloned DNA fragments which comprises the entire genome of an organism of an organism. Probes with DNA sequence complementary to the gene to be isolated are used. They bind with the desired gene making it visible and help in isolating it from the library. Cloning vectors are utilized to insert foreign DNA into another cell and create multiple copies of the same. A restriction enzyme is an enzyme that cleaves DNA into fragments at or near specific recognition s
