DNA Replication Proofreading activity to maintain the fidelity of DNA synthesis occurs in prokaryotes but not eukaryotes is a function of the 3'-5' exonuclease activity of the DNA polymerases occurs after the synthesis has been completed requires the presence of an enzyme separate from the DNA polymerases occurs in prokaryotes but not eukaryotes is a function of the 3'-5' exonuclease activity of the DNA polymerases occurs after the synthesis has been completed requires the presence of an enzyme separate from the DNA polymerases ANSWER DOWNLOAD EXAMIANS APP

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