What is the purpose of incubating purified DNA with restriction enzyme?
Options
- ATo check the progression of digestion
- BTo prepare recombinant DNA
- CTo charge the DNA molecule
- DTo release DNA from the cell membranes
Correct answer
B. To prepare recombinant DNA
Step-by-step solution
Restriction enzyme digestions are performed by incubating purified DNA molecules with the restriction enzyme, at the optimal conditions for that specific enzyme. Agarose gel electrophoresis is employed to check the progression of a restriction enzyme digestion. DNA is a negatively charged molecule, hence it moves towards the positive electrode (anode). The process is repeated with the vector DNA also. The joining of DNA involves several processes. After having cut the source DNA as well as the vector DNA with a spe
