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