• Failing to differentiate between prokaryotic and eukaryotic replication processes.

FAQs

Question: What is the structure of DNA?
Answer: DNA is composed of two strands forming a double helix, made up of nucleotides that include a phosphate group, a sugar, and a nitrogenous base.

Question: How does DNA replication occur?
Answer: DNA replication occurs through a semi-conservative mechanism where each strand serves as a template for the formation of a new complementary strand.
