unit 4 bio

cell communications and mitosis

QuestionAnswer
paracrine signaling releases signal molecule to cells in a near vicinity right to left (
hormonal and endocrine signaling are the same
plants use what to allow nutrients and signal molecules to flow between linked cells plasmodesma
short distance signaling paracrine signaling
animals use what to allow nutrients and signal molecules to flow between linked cells gap junctions
what are ligands or local regulators chemical messengers
what is an example of paracrine signaling synaptic signaling
synapse junction between 2 nerve cells
apotosis programmed destruction
plant cells do not create proteins or have a cleavage furrow during the process of cytokines
connects centro mere to spindle fiber kinetochore
checkpoint that verifies spindle fibers are connected correctly m checkpoint during metaphase
kinase adds phosphate group
phosphatases remove phosphate groups
synthesis where chromatids replicate
gtpase the hydrolysis of gtp to gdp
checkpoint verifys that dna is undamaged g1
3 checkpoints g1, g2, m
interphase is before or after mitosis before
uncoiled stringy DNA chromatin
how many pieces of CHROMATIN does each cell have 46
the result of mitosis is 2 genetically identical daughter cells
phases of mitosis are prophase, prometaphase, metaphase, anaphase, telophase
prophase chromatin condense and become visible and become chromosomes
each half of a chromosome is called a sister chromatid and they are identical
what does the nucleus do during prophase disengrates
what happens during metaphase chromosomes line up single file down the middle of the cell
what happens in anaphase sister chromatids split up and move towards opposite poles
what happens in the telophase 2 diploid daughter cells
