The stage of the cell cycle where the nucleus divides
The stage of the cell cycle where the cell PREPARES to divide
G1, S, G2,
- A.chromatin condenses to into visible chromosomes
- B. Mitotic Spindle form in cytoplasm between centriole pairs; lengthens as microtube grows.
- A. Nuclear Envelope fragments
- B. Mitotic Spindle invades Nucleus
- C. Microtubules bind chromatids at kinetochores
- A. Centrosomes at opposite ends of cell
- B. Chromosomes (attached to MT's) line up at metaphase plate (center of cell)
- Sister chromatids seperate and are pulled toward opposite poles.
- Kinetochore MT's shorten at the ends
- Motor proteins "walk" along MT's to pull chromatids
- non - kintochore MT's get longer and slide past each other
- A. Nuclear envelope reform (now two sepertare nuclei)
- B. Chromosomes partly unfold
- Cytokinesis (start during telophase)
Microfilaments under plasma membrane princh in; form cleavage fullow to squeeze cell in half
Duplicated chromosomes has 2 sister chromotids attacted at the centromere
Rectangular structures that are copied during the late part of interphase; pull on spindle fibers
Two of them make up a chromosome
What is the longest phase in cell cycle?
- Interphase, usually takes 18 hours
- The M phase takes about 6 hours
- It takes a cell one day to divide
What's the longest phase in mitosis?
The metaphase is the longest phase of mitosis
