M-Phase
Draw what happens in Anaphase.
I will judge this
90%
what is the definition of cancer
Uncontrolled cell growth
What is a stem cell
undifferentiated cell, or a cell without a job.
Who won the suns vs warriors game last night?
Warriors. boo
what is the phase that spindle fibers connect
Metaphase
What is the spaghetti noodle like DNA called when in interphase, before it thickens?
Chromatin
what are 3 common treatments for cancer
Chemo, radiation, surgery... ?
when do we have the most stem cells
Embryonic stage
A person gets a deep cut on their skin and needs to repair the damaged tissue. Which part of the cell cycle increases and why?
Mitosis, to replace the damaged tissue
what happens in prophase (I will accept the MOST correct answer so include everything that happens)
Chromosomes thicken, become visible, and the nuclear membrane disappears.
What are the three sub phases of interphase
G1, S, G2
Candy question!
what phase does the cell check to see if the spindle fibers are attached to the sister chromatids?
M-phase (specifically meta phase, within the M-phase)
what is the difference between Pluripotent, multipotent and unipotent?
Pluri =almost any cell
Multi= only a few types (white or red blood cells)
Uni = only one cell type (already specialized)
BONUS CANDY QUESTION.
Look at these three patient's biopsy results. determine which most likely has cancer and why?
Patient 1. Interphase 20, Prophase 1, metaphase 1, anaphase 0 , Telophase 1
Patient 2. Interphase 25, Prophase 2, Metaphase 2, Anaphase 2, Telophase 2.
Patient 3. Interphase 21, Prophase 1, Metaphase 0, Anaphase 1, Telophase 1
Patient 2 has the highest percent of cells in mitosis
patient 1 =13%
Patient 2 = 24%
Patient 3 = 12.5%
Animal cells squeeze in and form the cleavage furrow to form new cells, and plant cells form a cell plate down the middle.
What happens during the S phase of interphase
DNA is replicated (doubles)
when does the cell check that DNA was copied correctly and intact?
G2
True or false Once a cell is specialized or has a job, it can never do anything else?
True
what is the largest single cell in the world?
ostrich egg.
Candy Question!
where do the spindle fibers attach to the sister chromatids?
Centromere
What happens during G1 phase of interphase? (the most correct answer will get the points, so include everything that happens)
Doubles organelles, grows in size, continues normal functions.
what are the two genes we talked about that help prevent cancer
Proto-oncogenes and tumor suppressing genes (like P53)
where do the majority of stem cells come from?
donations from IVF treatments (leftovers from IVF)
If someone has blood cancer (leukemia) why would they need bone marrow transplant and not blood transplant? What type of cells are probably contained in bone marrow
hematopoietic stem cells or blood stem cells
