Which statement correctly describes the number of origins of replication in prokaryotic versus eukaryotic chromosomes?
Show answer and explanation
Correct answer: Prokaryotes have a single origin; eukaryotes have multiple origins
Prokaryotes (with circular chromosomes) typically replicate from a single origin of replication, whereas eukaryotic linear chromosomes use multiple origins to replicate large genomes efficiently.
