In eukaryotes, the DNA replication rate is 50 nucleotides per second. How long would the replication of a chromosome of 150 million base pairs take if eukaryotic chromosomes were replicated like those of prokaryotes? Actually, eukaryotic replication takes only several hours. How do eukaryotes achieve this high rate?
Assume that a certain bacterial chromosome has one origin of replication. Under some conditions of rapid celldivision, replication could start from the origin before thepreceding replication cycle is complete. How many replication forks would be present under these conditions?
A circular molecule of DNA contains 1 million base pairs. If the rate of DNA synthesis at a replication fork is 100,000 nucleotides per minute, how much time will theta replication require to completely replicate the molecule, assuming that theta replication is bidirectional? How long will replication of this circular chromosome by rolling-circle replication take? Ignore replication of the displaced strand in rolling-circle replication.
The speed of DNA replication at a replication fork is about 100 nucleotides per second in human cells. What is the minimum number of origins of replication that a human cell must have if it is to replicate its DNA once every 24 hours?
