Before direct proof of DNA being the genetic material,indirect evidence suggesting DNA as the appropriate macromolecule,included
A) Gametes have 1/2 the amount of DNA as somatic cells
B) Molecular composition of DNA is the same in different cells of an organism, whereas RNA and protein contents vary
C) A correlation between DNA content and the number of chromosome sets per cell
D) DNA is more stable than RNA or protein
E) All of these

Question

Quizplus · Accepted Answer

All of the given options suggest indirect evidence for DNA as the genetic material. Gametes having half the amount of DNA indicates that it is involved in inheritance. The molecular composition of DNA being the same in different cells implies its important role in cellular processes. The correlation between DNA content and the number of chromosome sets per cell suggests a connection between DNA and genetic material. Finally, DNA's stability hints at its essential role in genetic material.
