Question: 134. Match List-I with List-II.
| List-I | List-II |
|---|---|
| A. Alfred Hershey and Martha Chase | I. Streptococcus Pneumoniae |
| B. Euchromatin | II. Densely packed and dark-stained |
| C. Frederick Griffith | III. Loosely packed and light-stained |
| D. Heterochromatin | IV. DNA as genetic material confirmation |
Choose the correct answer from the options given below:
(1) A-II, B-IV, C-I, D-III
(2) A-IV, B-II, C-I, D-III
(3) A-IV, B-III, C-I, D-II
(4) A-III, B-II, C-IV, D-I
Answer: Option (4)
Explanation:
Alfred Hershey and Martha Chase conducted experiments that proved DNA is the genetic material.
Euchromatin is loosely packed chromatin and appears light-stained under a microscope.
Frederick Griffith worked on the bacterium Streptococcus pneumoniae and discovered the phenomenon of transformation.
Heterochromatin is densely packed chromatin and stains darkly.
Thus, the correct matching is A-IV, B-III, C-I, and D-II.
