Lab 11 Mitosis

Interphase - Chromosomes are not visible because they areuncoiled

Prophase- The chromosomes coil. The nuclear membranedisintegrates. Spindle fibers (microtubles) form. The drawing showsa cell with 8 chromosomes. Each chromosome has 2 chromatids for atotal of 16 chromatids.

Prometaphase

Metaphase - The chromosomes become aligned. The drawing shows acell with 8 chromosomes. Each chromosome has 2 chromatids for atotal of 16 chromatids.

Anaphase- The chromatids separate; the number of chromosomesdoubles. The drawing shows a cell with 16 chromosomes. Eachchromosome has 1 chromatid for a total of 16chromatids

Telophase- The cell divides into two. The chromosomes uncoil.The nucleus reforms. The spindle apparataus disassembles. Thedrawing shows a cell with 16 chromosomes. Each chromosome has 1chromatid for a total of 16 chromatids.
