Zoology-Recombinant DNA
NEET Zoology Recombinant DNA Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
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
Choose the correct matching:
A
a-iii, b-iv, c-ii, d-i
B
a-iv, b-iii, c-i, d-ii
C
a-ii, b-i, c-iv, d-iii
D
a-iii, b-ii, c-i, d-iv
Correct Answer
Option A
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.
