DNA (3.5 x 108 base pairs) in diploid cells of Drosophila melanogaster is replicated in about 3 minutes. Assuming that all replication forks move at a constant rate of 104 base pairs per minute, what is the minimum number of replication units present in the Drosophila genome?

In order to answer this question you must focus on what the units of the numbers provided are and then do some calculations to determine the answer. You must also understand what a replication fork and a replication unit is. In order for DNA to be replicated the double helix must first be unwound to produce two single strands of DNA. This occurs at the origin of ...
