Mitosis and Cytokinesis

mitosis

cell division that occurs in every cell in the body other than the sex cells

gametes

sex cells can be referred to as...

diploid

mitosis starts with what chromosome number

diploid

full chromosome number

2, diploid

after mitosis you will have how many daughter cells and what chromosome number

mitosis

division of the nucleus

cytokinesis

division of the cytoplasm

chromatin

what is the term used when the chromosomes are long, wrapped around each other and you can't tell one from another

chromosome

wound chromatin is termed

chromatid

1 strand of a double stranded chromosome

centromere

what holds together the chromatid

DNA and a histone protein

what are chromosomes composed of

chromosomes

by wrapping DNA around a histone protein you create what

chromatin

by unwrapping DNA from a histone protein you produce what

interphase

first part of the cell cycle

interphase

where will a cell spend most of it's life

3

how many phases are in interphase

G1 phase

first phase of interphase; cell grows in size

S phase

stage of interphase in which DNA is replicated

G2 phase

preparation for mitosis, producing anything needed for cell division

interphase

when are the nuclear membrane, the nucleolus, chromatin, and in animal cells centrioles present

prophase

what is the first phase in mitosis

prophase

when do the nuclear membrane and the nucleolus disappear

prophase

when does the chromatin shorten into chromosomes

prophase

when, in an animal cell, does the centriole split and turn into an aster

aster

a centriole that has split and formed astral, polar, and kinetichore fibers

polar fibers

spindle fibers that extend from aster to aster

kinetochore fibers

fibers that form from the aster to the middle of the cell also called traction fibers

spindle

the entire structure formed in prophase

metaphase

what is the second phase of mitosis

metaphase

when do the chromosomes line up in the middle of the cell

metaphase

when do the kinetichore fibers attach to the centromere of the centered chromosomes

anaphase

what is the third phase in mitosis

anaphase

when does the centromere of the chromosome split and the single stranded chromosomes move to the sides of the cell

telophase

what is the fourth phase in mitosis

telophase

when does the spindle disapper

telophase

when does the centriole reform, and the nucleolus and the nuclear membrane reform

telophase

when does the chromosome unwind into chromatin

telophase

during which phase of mitosis does cytokinesis begin

cell plate

in a plant cytokinesis will form when this is formed

pinches apart

in an animal cell, cytokinesis occurs when the cell...
