MCQ
Enzymes necessary for recombinant DNA technology are:
- AEndonucleases and polymerases
- BRestriction endonucleases and ligases
- CPeptidases and ligases
- DRestriction endonucleases and topoisomerases
Explanation:
Recombinant DNA technology is the method of joining two or more DNA molecules to create a hybrid. This technology is made possible by two types of enzymes, restriction endonucleases and ligase. A restriction endonuclease recognizes a specific sequence of DNA and cuts within, or close to, that sequence. DNA fragments generated by digestion with a restriction endonuclease can be joined together again by the enzyme ligase.
