Document Summary

U7-06 load s phase in cell cycle. S aka synthesis phase, is a part of interphase. In the s phase of interphase, the dna (as chromatin) replicates, with each chromosome producing 2 chromosomes, known as 2 sister chromatids. U7-06 load mitosis phases: prophase vs. metaphase vs. anaphase vs. telophase vs. interphase. Metaphase = condensed chromosomes line up in pairs along the plane halfway between the spindle poles (each chromosome pair are linked to different spindle poles via microtubules that extend between the spindle and the centromere) Anaphase = sister chromatids separate with each one being drawn toward the spindle pole to which it is connected. Telophase = when the process is completed and the 2 cells separate. Interphase = most of the cell life is in this stage where the chromatin is uncondense. Divided into the g1 (gap) phase, the s (synthesis) phase where dna is replicated and the g2 phase, where the replicated chromosomes cohere to each other.
