We're looking at the stages of the cell cycle, which is a percent of a cell cycle is an interface, which is made up of g1, s, and g2, and then the cell division process, which starts with nuclear division in mitosis, and then, of course, cytokinesis at the end of it.
00:20
And it states that the regulations of the cell cycle are involving various cyclones.
00:27
So there's two major classes of cyclones.
00:30
There's mitotic ones, and there's also g1 class of cyclones.
00:36
And out of these various classes, there are a bunch of different types, but there's four types that we're going to talk about today.
00:43
One of the types is the g1 cyclins.
00:46
A second type is g1 slash s cyclones.
00:51
The third is s cyclones, and the last is m cyclones.
00:56
And if you look at the answer choices, we have basically three choices.
01:02
And we can also immediately eliminate some of the options.
01:06
For example, question a says that the g1 slash s will be high.
01:12
And regardless of what the other thing is, question b says g1s slash s will be low.
01:20
And so between the two, we've got to decide are the g1 slash s going to be higher or low? and then regardless of what else is there, make that decision first of, is it going to be higher or is it going to be low? so on that note then, the g1 slash s should be low because if we're already transcribing, if we're already getting some of that dna to be replicated, then we're full all in to the s phase.
01:51
So we should be done with g1...
