Okay, for this question, we are looking at dna replication, and specifically there are some enzymes we're going to list here that are used in dna replication.
00:25
We have helicase, we have binding proteins, we have ligase.
00:40
So we have a strand of dna, so in it's double -stranded, all those bases, right? face in the middle here and it's wound up so here it would be in this helix shape by blinding but during dna replication it needs to unwind in order to replicate so that's where then these are going to be two strands split so the new strands can be added on okay so so in order for these strands to separate, we have here where they're getting separated.
01:45
This is where our helicase comes in.
01:50
And so the helicase is like a scissor.
01:54
So we're coming up with an analogy for how it acts.
01:57
It's like a scissor because it's splitting those two strands apart from one another.
02:05
So those bases are being separated, kind of cutting those strings.
02:08
Ties that they have binding those bases together.
02:13
So the helicase is like the scissor...
