2025 Molecular Basis of InheritanceGenetic Material and Chromatin Organization Easy Question 10 of 200 in Molecular Basis of Inheritance

Match List-I with List-II.

Column I

  • A. Alfred Hershey and Martha Chase
  • B. Euchromatin
  • C. Frederick Griffith
  • D. Heterochromatin

Column II

  • I. Streptococcus pneumoniae
  • II. Densely packed and dark-stained
  • III. Loosely packed and light-stained
  • IV. DNA as genetic material confirmation

Correct answer: A → IV, B → III, C → I, D → II

Solution

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

Hershey-Chase proved DNA is the genetic material using bacteriophages (IV). Euchromatin is loosely packed and transcriptionally active/lightly stained (III). Griffith performed transformation experiments using Streptococcus pneumoniae (I). Heterochromatin is densely packed and dark-stained (II).
