Indicate the stage of mitosis (interphase = I, prophase = P, metaphase = M, anaphase = A, telophase = T) during which each of the following events occur. chromatid doublets separate to individual chromosomescentriole replicatesreplicated chromosomes (chromatid doublets) are arranged in single file next to one another at the cell's equatornuclear membrane is disappearingspindle fibers form and become visiblecell plate (plant) or cleavage furrow (animal) forms and is visiblechromosomes are at opposite poles of the cell; cytokinesis is almost completedchromosomes (chromatids) first become visible as long thin strandsDNA (chromosome) replication occurs
What would happen if anaphase proceeded even thoughthe sister chromatids were not properly attached to theirrespective microtubules and lined up at the metaphaseplate?
Which phase is described below? The chromosomes condense, Each is made of two sister chromatids,(looks) like an "X" Each sister is a clone, the closest of kin, And acentromere connects them like siamese twinsThe nucleolus disappears it melts away, as the cell takes a ribosomeproduction holiday, the centrosomes separate, start spindle formationfor separating chromatids and cell elongation.
What will be the outcome if anaphase proceeded even thoughthe sister chromatids were not properly attached to theirrespective microtubules and lined up at the metaphaseplate?
Why would the supercoiled, condensed formof chromosomes seen in metaphase not besuitable for the G1 phase of the cell cycle?Why would the finely dispersed chromatinof the G1 phase not be suitable for mitosis?
Match these cell division phases with the appropriate processes Break down of the nuclear membrane [ Choose ] allowing mitotic spindles to connect to [Choose ] Telophase Metaphase Anaphase Prometaphase Cytokinesis Interphase kinetochores APC degrades securin which allows separase to become active which degrades the cohesin rings Dephosphorylation of nuclear pore and lamins cleavage of plasma membrane by actin and myosin contractile ring [ Choose ] copying of the genome [ Choose ] formation of the metaphase plate [Choose ]
At which phase of mitosis do the sister chromatids first become daughter chromosomes? O prophase O interphase O metaphase telophase anaphase
Nuclear envelope is present in _______?_______of cell cycle and _____?________ of mitosis .
Put the following phases of the cell cycle and mitosis in the correct order. Prometaphase Interphase - S phase Telophase Prophase Anaphase Interphase - G1 Metaphase Interphase - G2
