Explain how the complementary base pairing in DNA contributes to its replication process.

• Complementary base pairing allows DNA to form a stable double helix, preventing replication.

• Complementary base pairing ensures that each new DNA molecule is identical to the original, allowing for accurate replication.

• Complementary base pairing allows DNA to form a triple helix, facilitating replication.

• Complementary base pairing prevents mutations during replication by forming identical strands.

Which of the following best describes the process of DNA replication?

• DNA replication involves the conversion of DNA into RNA.

• DNA replication involves the synthesis of a new DNA strand complementary to the original strand.

• DNA replication involves the conversion of RNA into protein.

• DNA replication involves the degradation of DNA into nucleotides.
