cell division

QuestionAnswer
what are the two stages of cell division. mitosis and cytokinesis
what is the function of the mitotic spindle. help separate the chromatids
what is the cell cycle. the series of events that the cell goes through to grow and divide
what are the four phases of mitosis 1.prophase 2.metaphase 3.anaphase 4.telophase
what happens during prophase the chromosomes become visible the centrioles take up positions on opposite sides of the nucleus
what happens during metaphase the chromosomes line up across the center of the cell
what happens during anaphase the chromosomes move until they form two groups near the poles of the spindle
what happens during telophase a nuclear envelope re forms around each cluster of chromosomes the nucleolus becomes visible in each daughter nucleus
what is cytokinesis the division of the cytoplasm of the cell following the division of the nucleus
how does cytokineses occur in most animal cells the cell forms a cleavage furrow that tightens and splits the cell
in eukaryotic cells what are the two main stages of cell division division of the cells nucleus 2. division of the cells cytoplasm
when chromosomes become visible at the begining of cell division what does each chromosome consist of two identical sister chromatids
the division of the cells nucleus during the m phase of the cell cycle is called mitosis
interphase is divided into what three phases 1.g1 phase 2. s phase 3. g2 phase
what happens during the g1 phase increase in-size creates new proteins and organelles
what happens during the s phase chromosomes are replicated
what happens during the g2 phase organelles and molecules required for cell division are produced
which cells undergo cell division both prokaryotic and eukaryotic cells
what is the correct order of the cell cycle in an eukaryotic cell g1-s-g2-m
the correct order of a prokaryotic cell division is growth-DNA replication-chromosome segregtion
what happens during mitosis the nucleus of the cell divides
chromatid Either of the two strands joined together by a single centromere
centromere the center of the chromosome where the two chromatids touch
chromatin the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins
chromosomes stands of DNA stuffed in 2 chromatids that make an x shape
interphase the period of the cell cycle where the nucleus is not undergoing division
cyclin one of a family of closely related protiens that regulate the cell cycle in eukaryotic cells
cancer an uncontrolled growth of cells with the potential to spread and form colonies elsewhere in the body.
growth factor a substance that affects the growth of a cell
tumor a mass amount of cells that divide abnormally quickly and fail to carry out their usual function
embryo the earliest stage of a developing unborn individual in the uterus
stem cell a cell in the body that can divide to give rise to more cells.
differentiation a process which a less specialized cell becomes more specialized
cell division the division of a cell into two identical daughter cells with the same generic information
asexual reproduction a form of reproduction that doesn't involve miosis
sexual reproduction a form of reproduction involving the mating of a male and female sperm
the rate at which materials enter and leave the cell depends on the cells? surface area
in order for a cell to divide successfully the cell must first duplicate its genetic information
if a cell has 12 chromosomes how many chromosomes will each of its daughter cells have after mitosis and cytokenisis 6
in the plant cell what forms midway between the divided nuclei during cytokinesis cell plate
the timing in the cell cycle in eukaryotic cells is believed to be controlled by a group of closely related proteins known as cyclins
