00:02
So you have a circular dna which is 800 ,000 base pair.
00:08
So the dna replication proceeded at 5 ,000 base pair per second and there are two origin of replication.
00:13
There are 200 ,000 base pair apart.
00:15
How long would it take to replicate the entire chromosome? assume both origin initiate simultaneously.
00:23
So you have two origin of replication and there are 200 ,000 base pair apart.
00:30
You have two origin of replication.
00:31
You can see this is a replication bubble and the replication fork is going to move bidirectionally.
00:36
The one move upwards is going to finish first because there is shorter distance between the origin of replication to the middle.
00:48
So the red one, the red strand will be, the new strand will meet up in the middle first.
00:55
Now the green strand is going to extend downwards.
01:00
Again you have two origin of replication.
01:02
They're going to actually work on the same time and they will again meet up in the middle.
01:07
So the key here is to figure out how long would it take to finish the green strands because again green strand is longer than the red strand.
01:16
The red one will finish first but we'll have to know how long does it take to finish the bottom part of the chromosome...
