Read the following Assertion and Reason and choose the correct option. Assertion: Insertion or deletion of one or two bases changes the reading frame from the point of insertion or deletion, such mutations are referred to as frameshift insertion or deletion mutations. Reason: Insertion or deletion of three or its multiple bases insert or delete in one or multiple codon hence one or multiple amino acids , and reading

Options

  1. ABoth Assertion and Reason are true and Reason is correct explanation of Assertion
  2. BBoth Assertion and Reason are true but the Reason is not the correct explanation of Assertion
  3. CAssertion is true but the Reason is false
  4. DBoth Assertion and Reason are false

Correct answer

B. Both Assertion and Reason are true but the Reason is not the correct explanation of Assertion

Step-by-step solution

Insertion or deletion of one or two bases changes the reading frame from the point of insertion or deletion, such mutations are referred to as frameshift insertion or deletion mutations. Insertion or deletion of three or its multiple bases insert or delete in one or multiple codon hence one or multiple amino acids , and reading frame remains unaltered from that point onwards.
