19
Q

Special strands of microtubules which grow out of the centrioles, connect to chromosomes at te centromeres and pull them apart during (the anaphase) of mitosis.

A

Spindle Fibers

20
Q

what does cell reproduction accomplish?

A

replaces damaged or lost cells; allows for growth

21
Q

what is a chromosome?

A

DNA and (histone) protein coiled into thick filaments visible when cell divides in mitosis.

A

cleavage furrow

36
Q

A tiny cell structure that carries out a specific function within the cell

A

checks to see if a cell is healthy and has grown to a suitable size and if so proteins will initiate cell division.

A

G1 checkpoint

38
