Question

What is the primary reason DNA replication must be highly accurate during the S-phase?

विकल्प

• To ensure each daughter cell receives an identical copy of the genome

• To prevent the degradation of parental DNA strands

• To prevent the cell cycle from progressing too rapidly

• To maintain the structure of the cell nucleus

Answer 1

DNA replication must be highly accurate because every cell that divides must pass an identical copy of the genome to its daughter cells. Even a single error during replication results in a mutation, which is why fidelity is essential for maintaining genetic integrity across generations.
