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