replication of eukaryotic cells
where is DNA found?
in chromosomes
true or false- kinetochores bind centrosomes (middle of chromosomes) on side of condensed mitotic chromosomes. it does not help pull the two sister chromatids apart.
false. while the first part is true, kinetochores DOES help pull the two sister chromatids apart
mitosis happens in what two phases?
prophase, metaphase, anaphase, telophase
what are the two types of chromosomes ?
chromatin form and condensed mitotic chromosomal form
difference between diploid and haploid cells
diploid cells have two times the amount of chromosomes, 2N chromosomes, form plants and animal, 46 chromosomes
haploid cells egg and sperm have only one set of each (gametes), 1N chromosomes, 23 chromosomes, forms when diploid cells undergo meiosis
true or false. cytokinesis is the division of one cell into two. in animal cells cleavage furrow occurs to divide cell into two
true
what are some difference between chromatin form and condensed mitotic chromosomal form?
chromatin-not tightly packaged, make RNA copies, make DNA copies, not visible under microscope.
condensed-tightly packaged, cannot access DNA, division of two cells occurs before packaging, visible under microscope.
whats an example of homologous
answers may vary
example- birds and bats originate from the same structure and purpose.
what happens in prophase?
spindal
what occurs before mitosis division into sister chromatin?
sister chromatin attaches to the centrosomes middle of the centrosome
what are the three main phases of the cell cycle
interphase, mitosis, cytokinesis
true or false- histosones are proteins in chromosomes in that gives the chromosomes structure
true
what is G2 responsible for?
what is interphase responsible for?
what is G1 responsible for?
what is S phase responsible for?
what is mitosis responsible for?
G2-prepares cells for mitosis phases G1, S, G2
interphase- cell growth, synthesis
G1-cell grows larger to make two
S- DNA replicates to chromosomes
mitosis- splits into two daughter cells
