Hello everyone.
00:01
Today we'll be looking at a question about checkpoints.
00:03
So checkpoints that are part of the cell cycle.
00:06
Remember that the main function of the cell cycle is to make more cells.
00:11
But in order to make more cells, there's a few steps that we need to make sure are happening in between so that the cell that we do make is a healthy and viable cell.
00:22
So let's take a look at the cell cycle from the start.
00:24
First, we begin with the g1 phase.
00:27
So that's when the cell grows to its normal size.
00:30
Being, let's say, born right after being made.
00:35
After the cell grows to its normal size, it gets to this checkpoint, the g1 checkpoint, where we need to make sure that the cell has enough nutrients to continue with the cycle...
