Okay, what i said this question? let's talk about a double -stranded repair mechanisms.
00:06
Okay, when you have a double -stranded dna, and you have a damage to this double -stranded molecule, let's make it like this.
00:19
Imagine this is your dna molecule.
00:20
Okay? and this is an exogenous source, like ionizing radiation or, i don't know, radiotherapy.
00:30
For example, during treatment of cancer.
00:33
Damage to this dna or double standard dna okay so maybe this is going to happen this is going to happen okay so one way to fix this is called homologous and joining in this homology omology means similar structure so in this type of repair you're going to use a sister chromosome as a template so as you're going to use a sister chromosome as a template you're going to it is going to guide in order for this dna to be repaired with the guide of the template.
01:10
Okay, so it is very unlikely that this gripper has like a mistake or an error because you're using a template.
01:17
This is homologous and joining.
01:19
But also we have something called non -homologous in joining...
