this week in science we learned some new vocab.
chromatin's-unraveled DNA
chromosomes-organized DNA
chromotids-two chromosomes or sister chromosomes that form an "x" shape
centreol- create spindle fibbers
also we learned that it depends on the cell how many times it goes through its life cycle. for example, skin cells have a very fast life cycle when a heart cell's is very slow. in a cells life cycle a few things happen

1. they grow
2. replicate
3. mitosis

mitosis is basically when the cell splits into 2. it has 4 stages but some people say 6. the 4 main stages are...

• prophase
• metaphase
• anaphase
• telaphase

the two others are...

• interphase-before the 4
• cytokinesis- after the 4
