Reputation fork form, it all starts from the dna sequence.
00:06
So this is a double -stranded, double -heelic structure, dna.
00:10
And in a specific sequence inside of dna molecule, there is a origin of replication.
00:19
This is a specific dna sequence that will be recognized by certain protein to open up the replication fork.
00:26
So again, remember, origin of replication is a specific dna sequence.
00:29
So the next step, obviously, the protein that actually recognized the origin of replication and separate the dna strand is called helicase.
00:41
As you can see, the double -strand dna structure is being unwinded.
00:47
And then the enzyme actually recognized origin, then zip it, sort of separate them into two -step -strand, is called the helicase...
