How is bacterial DNA replication similar to eukaryotic DNA replication?

• A. Both involve the unwinding of the DNA double helix by helicase enzymes.
• B. Both occur in the nucleus of the cell.
• C. Both require the enzyme telomerase to complete replication.
• D. Both use multiple origins of replication on the DNA molecule.

Answer: (A)

Verified step by step guidance

1. Begin by understanding the basic process of DNA replication, which involves the unwinding of the DNA double helix, the synthesis of new DNA strands, and the eventual formation of two identical DNA molecules.
2. Recognize that both bacterial and eukaryotic DNA replication involve the unwinding of the DNA double helix by helicase enzymes. Helicase is crucial for separating the two strands of DNA, allowing each strand to be copied.
3. Consider the location of DNA replication: In eukaryotic cells, replication occurs in the nucleus, whereas bacterial cells, which lack a nucleus, perform replication in the cytoplasm.
4. Understand the role of telomerase: Eukaryotic cells use telomerase to extend the ends of linear chromosomes, but bacterial cells typically have circular DNA and do not require telomerase.
5. Examine the origins of replication: Eukaryotic DNA replication involves multiple origins of replication to efficiently replicate large genomes, while bacterial DNA usually has a single origin of replication due to its smaller size.
