Transcript 2) mitosis


There are 3 stages in the cell cycle:
1) INTERPHASE – cells grow and prepare to divide
2) MITOSIS – cells start to divide
3) CYTOKINESIS– two cells are formed from one

most the cell’s life is spent in this stage

normal cell activities take place

the DNA is in long, thin , invisible strands

DNA gets copied at the end of Interphase
There are 4 stages of Mitosis:
1 - Prophase
2 - Metaphase
3 - Anaphase
4 - Telophase

To make exact copies of cells




Each chromosome appears as two strands of
identical DNA
Each strand is called a chromatid
The nuclear membrane disappears
Think Well Mitosis Part 1

centrioles move to either side of the cell

chromosomes line up in the middle of the cell

sister chromatids separate

Each chromatid is called a ‘daughter’
chromosome

spindle fibres from centrioles pull them to
opposite sides of the cell

nuclear membrane starts to form around each
group of daughter chromosomes

cell appears to have 2 nuclei (nucleus)

The cell membrane pinches to make two new
daughter cells

Each cell is identical to the original parent cell
