DNA Replication The replication of chromosomes by eukaryotes occurs in a relatively short period of time because the eukaryotic replication machinery is 1000 times faster than the prokaryotes each chromosome contains multiple replicons the eukaryotes have more amount of DNA for replication eukaryotic DNA is always single stranded the eukaryotic replication machinery is 1000 times faster than the prokaryotes each chromosome contains multiple replicons the eukaryotes have more amount of DNA for replication eukaryotic DNA is always single stranded ANSWER DOWNLOAD EXAMIANS APP
