There is 3,000,000,000 base pairs and it needs to be replicated. The enzyme can replicate 60 base pairs/sec. If replication is finished in 20 mins (1200sec), how many origin of replications are there?

Question

anonymous · Answer

origin of replications means how many times replication occur??

ookawaiioo · Answer

yes

anonymous · Answer

i dunno but i m getin ans dat 4166 approx can be divided if proces goes like dis

ookawaiioo · Answer

I got 41666.67 origins of replication

3X10^9 bp/ [(60 bp/sec) * # of origin of replication = 1200 sec

The rate of replication is slow, so it must be eukaryotic system. Every origin  gives two replication fork. you need to divide your answer by two. i.e. 20833.3 aprrox to 20834

anonymous · Answer

yep, adeshshendge is right. I would draw the conclusion that you have got a prokaryotic system, no eukaryotic. I guess he already meant that. =) remember: circular DNA --> 2 replication forks per ori!
