NEET Zoology Recombinant DNA Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Exonucleases | (i) Specific recognition sequence |
| (b) Endonucleases | (ii) Elimination of non-transformants |
| (c) Selectable marker | (iii) Removal of nucleotides from ends |
| (d) Palindromic sequence | (iv) Cuts within DNA strands |
a-iii, b-iv, c-ii, d-i
a-iv, b-iii, c-i, d-ii
a-ii, b-i, c-iv, d-iii
a-iii, b-ii, c-i, d-iv
Correct Answer
Detailed Explanation
Exonucleases remove nucleotides from the ends of DNA, while endonucleases make cuts within the DNA strands at specific recognition sequences. A selectable marker helps eliminate non-transformants. Palindromic sequences are recognized by restriction endonucleases.
