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 eukaryotic DNA is always single stranded the eukaryotes have more amount of DNA for replication each chromosome contains multiple replicons the eukaryotic replication machinery is 1000 times faster than the prokaryotes eukaryotic DNA is always single stranded the eukaryotes have more amount of DNA for replication each chromosome contains multiple replicons ANSWER DOWNLOAD EXAMIANS APP
