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