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.DNA as genetic material confirmation

Choose the correct answer from the options given below:

  1. A

    A-III, B-II, C-IV, D-I

  2. B

    A-II, B-IV, C-I, D-III

  3. C

    A-IV, B-II, C-I, D-III

  4. D

    A-IV, B-III, C-I, D-II

Solution

Matchings:

  • Hershey and Chase — experimentally confirmed DNA as the genetic material using bacteriophage (IV).
  • Euchromatin — loosely packed, lightly stained chromatin (III).
  • Frederick Griffith — transformation experiments with Streptococcus pneumoniae (I).
  • Heterochromatin — densely packed and dark-stained (II).

A-IV, B-III, C-I, D-II.
