It's actually hard to see if you have just a simple microphone For most of a cell's life, the chromosomes are completely unwound. So that they're easy to see from a traditional or a But during interphase, the chromosomes aren't tightly bound like that This would be another chromosome right over here in magenta. Seeing DNA all tightly bound, or chromosomes all tightly bound like that and like that or like this,
This, in this orangeish color, I have the nuclear membrane You have all of the, all of the cytosol, and then Or not nuclear membrane, I have its cell membrane. So this right over here, actually let me, I did It's necessary in orderįor the cell to replicate, but you see it's a much smaller fraction. Shorter part of its life, a small fraction, a very interesting part. It's living, growing, producing proteins, whatever other functions it has and mitosis, it's a Its life in interphase and that's where it's just
So as you see, and this isn't precise, a cell spends most of It's the process by which the nucleus turns into two nuclei, but then that's obviously At some point it will be ready to divide and it will undergo mitosis. So I'm gonna make it like a cycle so it's gonna go back on itself. So let's say this is a new cell and it will go through interphase. Interphase is where a cell spends most of its life. Let's talk a little bit about the life cycle of a cell.
