Studied by 6 peoplesister chromatids are moving apart
anaphase
the nuclear membrane fades from view
prophase
a new nuclear membrane is formed around the chromosomes
telophase
the cytoplasm of the cell is being divided
telophase
the chromatin is found in the nucleus
interphase
the chromosomes are located at the equator of the cell
metaphase
the spindles disappear
telophase
animal cells begin to pitch in
telophase
the spindle is formed
prophase
chromatids line up along the equator
metaphase
chromosomes are not visible
interphase
cytokinesis begins
telophase
the cell plate in plants begins to form
telophase
the reverse of prophase
telophase
in what phase does the cell begin to split the cytoplasm and daughter cells first become visible in mitosis?
telophase
during what phase of mitosis do centromeres divide and the chromosomes move toward their respective poles?
anaphase
what is the phase where chromatin condenses to form chromosomes?
prophase
what is the name of the structure that connects the two sister chromatids?
centromere
in a chromosome pair connected by a centromere, what is each individual chromosome half called?
sister chromatid
what is the step of cell division where 2 identical daughter cells are formed?
cytokinesis
which phase of the cell cycle occurs when the cell is preparing to divide so it grows in size making organelles and copying DNA?
interphase
what forms across the center of a plant cell near the end of telophase?
cell plate
what is the division of the cytoplasm called?
cytokinesis
during this phase chromosomes line up in the middle.
metaphase
how can you differentiate animal and plant cells in the cell cycle?
animal cells are round while plant cells are boxy and rectangular. animal cells form cleavage when in anaphase and plant cells form cell plates when in anaphase.
what is the longest phase of the entire cell cycle?
interphase
what is the longest phase in mitosis?
prophase
why is mitosis important?
for the growth and development of our body cells
why is cell cycle regulation important?
to ensure that cell reproduction is correct so that cancers to form from mutations; irregularities can be corrected
what are cyclins?
a family of proteins that regulate the cell cycle in eukaryotic cells
what are the differences between internal and external regulators?
internal regulators respond to processes inside the cell. an example of an internal regulator is p53. external regulators respond to processes outside the cell. an example of external regulators are growth factors
what is cancer?
when the body loses the ability to control cell growth; uncontrolled mitosis
give different treatment options for individuals diagnosed with cancer
chemotherapy- compounds injected in the blood stream
radiation- targeted waves to reduce cancer in localized areas
surgery- only if the cancer is localized
list characteristics of cancer cells to look out for when using a microscope.
large distorted nucleus
large clumps of cells
lots of cells
abnormal shape
what is apoptosis? why is this important to the cell cycle?
apoptosis is programmed cell death. apoptosis is used to kill cells that are mutated, or cells with abnormalities.
mitosis is the division of _________ cells.
body/eukaryotic
