Phases
Phases 2
WILD
100
transport of substances occurs more easily in a...?
small cell
100
what happenes during G1 phase?
cell grows and develop
100
what is a chromatid?
2 identical parts of a chromosome.
100
what is/occurs during anaphase?
-centromeres split -sister chromatids are pulled to opposite sides -endswhen chromosomes stop moving
100
which mitosis phase requires the longest time?
interphase
200
once a cell reaches its limit, what will it so?
1. stop growing 2.divide
200
what happenes during S phase
DNA replication
200
what is a centromere?
the middle part of the chromosome that holds together the sister chromatids
200
what is/occurs during telophase?
-nuclear membrane reforms -spindles and centrioles break apart
200
what is mitosis?
separation of the cell's replicated DNA, resulting in 2 daughter cells that are genetically identical
300
what is the result of the cell cycle?
new cells
300
what happens during G2 phase?
organelles like spindle fibers and centriols are created.
300
what does IPMATC stands for?
I-interpahse P-prophase M-metaphase A-anaphase T-telophase C-cytokinesis
300
what is/occurs during cytokinesis?
-division of the cytoplasm
300
what is the ration of surface area to volume?
as a cell grows, its volume increases much more rapidly than surface area.
400
each times a cell goes through one complete cell cycle, what happenes?
it becomes two cells
400
what occurs during M phase?
-cells nucleus and nuclear material divide.
400
what is/occurs during the propahse?
-longest phase -chromosomes appear -chromosomes attach to spindle -nuclear membrane breakes down
400
a cell with 10 chromosomes undergoes mitosis and cell division. how many dauhther cells produced and what # of chromosomes do they have?
2 cells, 10 chromosomes each
400
What is cancer?
uncontrollable cell growth
500
what does interphase includes?
G1, S, G2
500
what is a chromosome?
stracture that contains genetic information.
500
what is/ occurs during the metaphase?
-shortest pahse -chromosomes line up at the center of cell
500
cytokinesis begins in?
telophase
500
Why are embryonic stem cells controversial?
There are alot of ethical issues.
