WebbPlease help me to lay out the steps of mitosis: prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis. Here, I have beads, so if you can kindly mark the color and use circles on your drawing (because some have 3 beads and some have 4), that would be a tremendous help! WebbS is the period of DNA synthesis, where cells replicate their chromosomes. G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs. M is the actual period of cell division, consisting of prophase, metaphase, anaphase ...
