And so what happens is each one of these chromosomes will be replicated during the f phase. And when we're going to get to the metaphase, those tetromer pairs will line up along the equator. So this will be replicated. And so what we form is the following two sister identical cystic, sister chromatids. This one will replicate as well. We're going to form two identical cystochromatids, and each one of these will also replicate it, but they will be found somewhere below or somewhere above that equatorial line.
