Watch Me!!!

Mitosis and the Cell Cycle:

Chromosomes condenseChromosomes appear as sister chromatids joined at the centromere Centrosomes move away from each other and the mitotic spindles begin to form

Nuclear envelope breaks apartMicrotubules (from the mitotic spindle) attach to each chromosome

Sister chromatids line up on the metaphase plate (roughly the middle of the cell)Centromeres at opposite poles of the cell

Sister chromatids seperate and are pulled to opposite poles as the microtubules shortenCell enlongates

Telophase: 2 nuclei with complete sets of DNA form at the poles of the cellNuclear envelopes formCytokinesis:Cytoplasm divides and 2 daughter cells are formed

The 3 stages of interphase will be discussed in detail next lesson!

Look at this!

Assignment: Watch the video.Read the important points of each mitotic step. Come up with 2 questions concening mitosis and the cell cycle for next class.
