WebEukaryotic cells store their DNA in the form of linear chromosomes. This creates problems for replication of DNA at the ends of the chromosomes because DNA polymerase can only synthesize DNA in the 5' to 3' direction. Suppose actively dividing eukaryotic cells were treated with a chemical that blocks the activity of the enzyme telomerase. WebThere are multiple origins of replication on the eukaryotic chromosome; humans can have up to 100,000 origins of replication. The rate of replication is approximately 100 nucleotides per second, much slower than prokaryotic replication.
