In what ways chromosomal dna replication in eukaryotes differ from DNA replication in prokaryotes. Detail answer required.
Solution:
The main difference between eukaryotic and prokaryotic DNA replication is unidirectional and bidirectional mode of replication respectively.
Prokaryotic cells contain a unique origin and DNA replication proceeds bidirectionally from the origin to the terminus. Therefore, the whole prokaryotic genome is a single replicon and the synthesis is continuous. On the other hand, eukaryotic cells contain multiple replication origins on single chromosome and hence many replicons.
A unit of DNA in which replication starts from a origin and proceeds bidirectionally or unidirectionally to terminus site is called a replicon.
