describe the two consequences of cell division
duplication of nuclear material and formation of two genetically identical cells
describe the two consequences of cell division
duplication of nuclear material and formation of two genetically identical cells
during this phase, spindle fibers disappear, nuclear envelope and nucleoli form, and teh chromosomes lenghten and become invisible
telophase
phase where spindle fibers shorten and the daughter chromosomes are pulled to the opposite end of the cell
anaphase
during this phase, spindle fibers disappear, nuclear envelope and nucleoli form, and teh chromosomes lenghten and become invisible
telophase
the constricted region where two daughter chromatids are attached is called the_____
centromere
phase where spindle fibers shorten and the daughter chromosomes are pulled to the opposite end of the cell
anaphase
cell plate forms and the cell is divided into two cells during this stage
cytokinesis
the constricted region where two daughter chromatids are attached is called the_____
centromere
the centromere that connect the two sister chromatids separate at the end of this phase
metaphase
cell plate forms and the cell is divided into two cells during this stage
cytokinesis
the centromere that connect the two sister chromatids separate at the end of this phase
metaphase
list the four stages of mitosis
prophase, metaphase anaphase, telophase
list the four stages of mitosis
prophase, metaphase anaphase, telophase
mitosis is the division of the _____
nucleus
mitosis is the division of the _____
nucleus
this phase is the time between cell division
interphase
this phase is the time between cell division
interphase
chromosomes duplicate during this phase
interphase
chromosomes duplicate during this phase
interphase
when does the coiling and condensation of chromosomes begin
interphase
this is the phase when the nuclear envelope and nucleoli disappear
prophase
list the three processes that make a complete cell cycle
interphase, mitosis, cytokinesis
this phase is when the chromosome becomes visible under the microscope
prophase
changes in genetic info during cell division
mutation
this phase is when microtubules form into spindle fibers
metaphase
ths phase is when chromosomes are lined up on the equator
metaphase
the spindle fibers formed during metaphase is attached to
centromere
explain interphase
time between cell division
chromosomes are duplicated
coiling and condesation of chromosomes, duplicated chromosomes attach to centromere
explain prophase
chromosomes shorten/thicken become visible, n. envelope & nucleoli disappear
explain metaphase
chromosomes line up in middle, spindle fibers form, at end centromeres separate
explain anaphase
spindle fibers shorten, daughter chromosomes form at opposite ends/separate
explain telophase
n. envelope and nucleoli form, spindle fibers disappear, chromosomes lengthen and become invisible
explain cytokinesis
division of cells, cell plate, wall forms, organelles are divided
_____ condenses to form chromosomes
chromatin, mixture of dna and protein
