Questions and Answers

Explain DNA replication process in cells.

DNA replication is the process by which the genome’s DNA is copied in cells before cell division, ensuring that each resulting daughter cell has its own complete genome.

How does the DNA double helix act as a template for its own duplication?

The nucleotide A pairs only with T, and G pairs only with C, allowing each strand of DNA to specify the sequence of nucleotides in its complementary strand by DNA base-pairing, thus enabling precise copying of the DNA molecule.

What is the significance of the chemistry of DNA synthesis in replication?

The addition of a deoxyribonucleotide to the 3′ end of a polynucleotide chain allows for the synthesis of a new DNA strand.
