Match List I with List II.

List IList II
A. Alfred Hershey and Martha ChaseI. Streptococcus pneumoniae
B. EuchromatinII. Densely packed and dark-stained
C. Frederick GriffithIII. Loosely packed and light-stained
D. HeterochromatinIV. Confirmation of DNA as genetic material

Choose the correct answer from the options given below:

  1. A.A-II, B-IV, C-I, D-III
  2. B.A-IV, B-II, C-I, D-III
  3. C.A-IV, B-III, C-I, D-II✓
  4. D.A-III, B-II, C-IV, D-I

Solution

Hershey and Chase confirmed DNA as the genetic material (IV); euchromatin is loosely packed and lightly stained (III); Griffith worked with Streptococcus pneumoniae (I); heterochromatin is densely packed and dark (II).
