Cell contains 1 set of unreplicated chromosomes A Process 1 A What has happened during Process 2? Cell contains 1 set of replicated chromosomes B Process 2 Cell contains 1 set of unreplicated chromosomes Cell contains 1 set of unreplicated chromosomes C The parent cell replicates its DNA so that it can divide the copies into genetically identical cells. The parent cell is divided into two smaller, equally sized cells that are identical to each other and the parent cell. The parent cell is joined with other cells, and then divides into two smaller sized cells that are genetically different from one another. The parent cell is growing larger and replicating the organelles to make sure each new cell gets an organelle of each type.

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.
The cell above is a lung cell of a salamander. In which stage of mitosis is it? What are the structures visible in green and blue fluorescence?
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
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?
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?
When studying living cells in a laboratory, researchers sometimesuse drugs as a way to cause cells to remain in a particular phaseof the cell cycle. For example, aphidicolin inhibits DNA synthesisin eukaryotic cells and causes them to remain in the G1 phasebecause they cannot replicate their DNA. In what phase of thecell cycle—G1, S, G2, prophase, metaphase, anaphase, or telophase—would you expect somatic cells to stay if the followingtypes of drug were added?A. A drug that inhibits microtubule formationB. A drug that allows microtubules to form but prevents themfrom shorteningC. A drug that inhibits cytokinesisD. A drug that prevents chromosomal condensation
A) Quiescent Anaphase Telophase Telophase phase Metaphase Prometaph The maternal and paternal chromosomes of each homologous pair separate and reach the poles of the cell, nuclear envelopes form around them, and cytokinesis follows to produce daughter cells.
