13) The correct option is d. Translocations.
A mechanism, which causes a gene to move from one linkage group to another is known as translocation.
14) The correct option is c. migrate more slowly than.
Smaller molecules migrate with the help of gel more rapidly than larger fragments, which migrate more slowly.
15) The correct option is d. DNA ligase is necessary for creating recombinant plasmids.
DNA ligase is used in laboratories for the formation of recombinant DNA . It is used in gene cloning to join DNA molecules together to form recombinant DNA.
16) The correc t option is a. They do not contain exons.
DNA sequences within a cDNA library do not contain exons.
