1
When chromosomes form they condense
and wrap around proteins called cyclins.
and intermingle with other chromosomes.
and leave the nucleus.
and the DNA wraps around tiny proteins called histones.
2
normal cells become cancer cells when
cells are influenced by the wrong cells
cells do not respond to checkpoints
a bacteria infects the cell
the dna in the cell will not divide
3
multipotent stem cells can become
cells of a closely related cell family.
any kind of cell.
multiplication tables.
irritated with lack of effort.
4
Spindle fibers are made of microtubules which are considered
carbohydrates
nucleic acids
lipids
proteins
5
The spindle fiber said
come with me chromatid.
sometimes I don't like being associated with the centrioles.
I am not a lipid
I am a microtubule. I am made of protein.
6
cell differentiation is
when a cell becomes specialized.
when a cell becomes ostracized.
when an immune system can recognize cancer cells from normal
a cell that is embryonic.
7
Apoptosis is
your dad's toes.
when cells migrate towards a water source.
when cells self destruct.
when you have a breakfast of nothing but pop and toast.
8

prophase
12
Chromatids are
chromosomes that will be discarded.
reduced versions of chromosomes.
parts of chromosomes that will crossover.
chromosomes that have been copied and have an exact match.
