During metaphase, what may happen if spindle fibers (kinetochore microtubules) will not be attached at the centromere via the kinetochore? o the cell will be arrested at G zero phase the DNA will be fully distributed to all daughter cells the number of DNA will be divided to two daughter cells One of the daughter cells may not contain any DNA at all

Describe the critical events of mitosis that are responsible for ensuring that each daughter cell receives a full set of chromosomes from the parent cell.
During anaphase of Mitosis, how do the chromosomes travel to the opposite ends of a dividing cell? O the centrosomes are constantly digesting spindle fibers making it shorter pulling the chromosomes nearer to the opposite ends of the cell the chromosomes are constantly traveling down the spindle fibers by digesting the fibers at the kinetochore O the chromosomes are twisting the spindle fibers making it shorter so that they may travel closer to the centrosome the centrosomes "reel" in the chromosomes using the attached spindle fibers
Centrioles at opposite end of cell Spindle fibres attached to centromeres 46 double stranded chromosomes lined up along the metaphase plate Diploid cell 2n = ANAPHASE Centrioles at opposite poles Spindle fibres attaches to centromeres of the single stranded chromosomes 46 chromosomes get separated - 46 chromatids get pulled to each pole by spindle fibres Diploid cell 2n =
The duplicated chromosomes are seen lined up in the center of the cell during prophase metaphase telophase anaphase s-phase
A sexually reproducing organism has the following phenotype DdEeAaTt. The D and E loci are on the same arm of a metacentric chromosome in the cis configuration. The A locus is on the long arm of an acrocentric chromosome and the T locus is on a telocentric chromosome. There are no other chromosomes. Show a diagram of the cell in metaphase of mitosis and the result of mitosis.
Which of the following sentences is CORRECT: O Nuclear envelopes re-form in anaphase II Nondisjunction can occur in the meiosis I or meiosis II, or during mitosis During metaphase I the chromosomes move to the opposite poles of the cells is the site of phospholipids, lipids, and steroid synthesis O golgi appratus rough endoplasmic reticulum smooth endoplasmic reticulum

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
In meiosis, fully formed spindle fiber can be found in - O only Metaphase I in plant cells Metaphase I and Anaphase I in plant cells O Metaphase I and Metaphase II in only animal cells O Metaphase I and Metaphase II in only plant cells O only Metaphase I in animal cells O Metaphase I and Metaphase II in both plant and animal cells
How does mitosis result in daughter cells containing identical number and same DNA with its parent cell? O Crossing over occurs during the g1 phase O Crossing over occurs during prophase I Crossing over does not occur during prophase Crossing over does not occur during metaphase
