Question

Assuming that the rate of DNA replication in human cellsis similar to that in fruit fly cell,calculate how long it would take to replicate the entire fruilt ty haploid (base pairs-8.25x10) Replication time-20.6 minutes Incorrect First let us calculate how many replication forks would be active in a typical fruit fly haploid cell replicating approximately 825×107 bp of DNA. If each replication fork is producing 100 base pairs per second it would take: b How many molecules of DNA polymerase does each cell need to carry out this task? Number of DNA polymerase molecules molecules X If there are two molecules of DNA polymerase per replication fork, the cell would require 1.10x10 DNA polymerase molecules Incorrect Submit Answer Try Another Version 9 item attempts remaining Previous Nex Save and

Explanation / Answer

A. The rate of replication in humans is 50 nucleotides per second.

No. Of base pairs in fruit fly=8.25×107

So, time required=0.02×8.25×107=0.165×107 seconds =458.33 hours
