A molecule that can act as a genetic material must fulfill the traits given below, except

Options

  1. AIt should be unstable structurally and chemically
  2. BIt should provide the scope for slow changes that are required for evolution
  3. CIt should be able to express itself in the form of 'Mendelian characters'
  4. DIt should be able to generate its replica

Correct answer

A. It should be unstable structurally and chemically

Step-by-step solution

A molecule that can act as genetic material must fulfill the following criteria: i) It should chemically and structurally be stable. ii) It should be able to generate its replica (replication). iii) It should provide the scope for slow mutation that are required for evolution. iv) It should be able to express itself in the form of Mendelian characters. The genetic material should be stable enough not to change with different stages of life cycle, ago or with change in physiology of the organism. DNA being more stab
