Question

Which of the following criterion needn’t be fulfilled by the genetic material?

(a) Occurrence of replication

(b) Should be able to express itself in the form of “Bohr’s characters”

(c) Provision of scope for the mutation that is required for evolution

(d) It should be chemically and structurally stable

I got this question in a national level competition.

This question is from Properties of Genetic Material (DNA versus RNA) topic in chapter Molecular Basis of Inheritance of Biology – Class 12

Answer 1

The correct choice is (b) Should be able to express itself in the form of “Bohr’s characters”

For explanation I would say: A genetic material must be both chemically and structurally stable. It must be able to replicate. It should provide scope for the evolutionary changes. But it should also be able to express itself in the form of “Mendelian characters” and not “Bohr’s characters”. These Mendelian characters refer to the three laws that were proposed by Gregor Mendel.
