Given below are two statements: Statement I : In living organisms, the initiation of DNA replication can occur randomly at any location along the length of the DNA molecule. Statement II : A specific DNA sequence called the origin of replication is strictly required for the replication process to begin. In the light of the above statements, choose the correct answer from the options given below:

Options

  1. ABoth Statement I and Statement II are correct
  2. BBoth Statement I and Statement II are incorrect
  3. CStatement I is correct but Statement II is incorrect
  4. DStatement I is incorrect but Statement II is correct

Correct answer

D. Statement I is incorrect but Statement II is correct

Step-by-step solution

DNA replication does not initiate randomly at any location along the length of the DNA molecule. It begins at specific regions known as the origin of replication. Therefore, Statement I is incorrect. A specific DNA sequence called the origin of replication is strictly required for the replication process to begin. The replication machinery recognizes this sequence to initiate the process. Therefore, Statement II is correct. Hence, Statement I is incorrect but Statement II is correct. Answer: Statement I is incorrec
