Which of the following is not a true statement comparing prokaryotic and eukaryotic DNA replication? Both eukaryotic and prokaryotic DNA polymerases build off RNA primers made by primase Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome DNA replication always occurs in the nucleus Eukaryotic DNA replication involves more polymerases than prokaryotic replication.
