Botany-DNA Structure

NEET Botany DNA Structure 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) Nucleosome (i) DNA packaging unit (b) 15 N isotope (ii) Heavy DNA in experiments (c) DNA length (iii) Comparison with nuclear size (d) Centrifugation (iv) Separation technique used

Choose the correct matching:

A

a-i, b-ii, c-iii, d-iv

B

a-ii, b-i, c-iv, d-iii

C

a-iii, b-iv, c-i, d-ii

D

a-iv, b-iii, c-ii, d-i

Correct Answer

Option A

Detailed Explanation

The nucleosome is a fundamental unit of DNA packaging, while the 15 N isotope was used to create heavy DNA in Meselson and Stahl's experiment. The comparison of DNA length with nuclear size highlights the challenge of DNA packaging, and centrifugation is indeed a technique used to separate materials based on density.
