interphase - nucleus appears normal and the cell is performing its usual cellular functions
interphase - cell is increasing all of its components, including organelles as the
mitochondria, ribosomes and centrioles
where does DNA replication occur - end of interphase
chromosomes which contain DNA are duplicated and contain two chromatids (sister
chromatids) held together at the - Centromere
the nucleus divides during - Mitosis
cytoplasm divides is called - cytokinesis
what happens during cytokinesis - two daughter cells are produced
during sexual production another form of division occurs - meiosis
Meiosis is a part of - gametogenesis production of gametes(sex cells)
results of meiosis - daughter cells have half the number of chromosomes as the parent
cell
results of mitosis - daughter cells have the same number of chromosomes and genetic
material as the parent cell
what can chromosomes exchange during cross over - genetic material
how many stages are there to the cell cycle - 4
name the four stages - G-1
, S
G-2
M
what occurs during G-1 stage - growth
what occurs during S stage - chromosomes are duplicated
what occurs during G-2 stage - prepares for cell division
what occurs during M stage - cell divides
explain why it is called the cell cycle process - ordered sequence of events that extends
from the time a cell is first formed from a dividing parent cell until it is own division into 2 cells
Mitosis - nuclear division that results in two new nuclei, each having the same number of
chromosomes as the original nucleus
parental cell - the cell that divides
daughter cell - results of parental cells dividing
If parental cell has 46 chromosomes how many chromosomes does each daughter cell have
following mitosis - 46
when cell division begins, chromatin starts to condense and compact to form - visible
rodlike sister chromatids held together at the centromere
DNA replication results in - duplicated chromosome, that consists of two sister
chromatids held together at a centromere
spindle - a structure that appears and brings orderly distribution of chromosomes to the
daughter cell nuclei
spindle - has a fiber that stretch between two poles(end), bundles of microtubules,
protein cylinders found in the cytoplasm that can assemble and disassemble
centrosome - main microtubule organizing center of the cell, divides before mitosis so
that each pole of spindle has a pair of centrosome
nucleus - large organelle containing the chromosomes and acting as a control center for
the cells
