Verified step by step guidance

Understand the context of DNA replication in prokaryotes and eukaryotes. Prokaryotes are simpler organisms, often with a single circular chromosome, while eukaryotes have multiple linear chromosomes.

Consider the cellular machinery involved in DNA replication. Prokaryotes have fewer regulatory mechanisms and simpler replication machinery, which can lead to faster replication rates.

Recognize that the rate of DNA replication is influenced by the complexity of the organism. Eukaryotic cells have more complex structures and processes, which can slow down the rate of DNA replication compared to prokaryotes.

Compare the replication processes: In prokaryotes, replication can occur at a rate of approximately 1000 nucleotides per second, whereas in eukaryotes, it is typically around 50-100 nucleotides per second.

Conclude that due to the simpler structure and fewer regulatory processes, the rate of elongation during DNA replication in prokaryotes is much faster than in eukaryotes.
