cell cycle

what phase do we cut to release?

anaphase

what is a chromatid

chromosome

if theres 40 chromatids, how many centromeres are needed to hold that together?

20

96 chromatids at metaphase, how many are gonna be in each nucleus in each new cell?

96/2

mitosis phases

-prophase

-prometaphase

-metaphase

-anaphase

-telophase

in which phase do we see centromeres first?

prophase

which phase takes the longest to setup/complete?

metaphase

what phase do we see uncoupling of sister chromatids?

anaphase

what has to be built first during cytokinesis?

cell plate

cancer cells may not need what to grow

growth factors

cancer cells can make their own

growth factors

cell division

continuity of life is based in reproduction of cells

all dna in cell constitutes cell’s

genome

dna molecules in dell are packaged into

chromosomes

how many chromosomes in cell nucleus for human?

46

somatic cells

have 2 sets of 23 chromosomes, 1 set of 23 inherited in each parent

centromere

narrow “waist” of the duplicated chromosome where 2 chromatids are closely attached

chromosomes line up in middle during

metaphase

cytokinesis

occurs in animal cells by cleavage

last step of cytokinesis in plant celks

forming of cell plate

binary fission

cell division for bacteria

protein kinase must be attached to cyclin to what

be active

regulatory proteins involved in cell cycle control

-cyclins

-cyclin-dependent kinases (cdk)
