Which of the following statements is TRUE? None of these are TRUE Interphase chromosomes are loosely compacted, overlapping, and intertwined with each other within the nucleus. Radial loops in the condensing chromosome are formed due to interactions between 30 nm fibers and the scaffolding proteins of the nuclear matrix - producing the 300 nm fiber of the chromosome Interphase chromosomes are loosely compacted and do not associate with histones until the cell is preparing to divide. Interphase chromosomes are also known as euchromatin. Condensed, metaphase chromosomes are also known as heterochromatin.

O Interphase chromosomes are loosely compacted and do not associate with histones until the cell is preparing to divide. O Interphase chromosomes are also known as euchromatin. Condensed, metaphase chromosomes are also known as heterochromatin.

Beginning with the G1 phase of the cell cycle, describe the levelof compaction of the eukaryotic chromosome. How does thelevel of compaction change as the cell progresses through thecell cycle? Why is it necessary to further compact the chromatinduring mitosis?
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?
Draw and label G1 and G2 stages of interphase and each stage of mitosis (in order) for a cell that has two large and two small chromosomes, 2n=4. For unreplicated chromosome draw a line ( / ) and for replicated chromosome draw an X. Since we are focusing on the DNA, you can skip drawing the nuclear membrane or spindle fibers. For simplicity, do not indicate that the chromosomes are decondensed chromatin during interphase. Mark and label a place on one of the large chromosomes with the dominant allele of the “A” gene and put the recessive allele “a” on the other homolog. Mark and label a place on one of the small chromosomes with allele “B” and put the recessive allele “b” on the other homolog.

HOW DO WE KNOW? how chromosomes are distributed during cell division, both in dividing somatic cells (mitosis) and in gamete- and spore-forming cells (meiosis). We found many opportunities to consider the methods and reasoning by which much of this information was acquired. How do we know that mitotic chromosomes are derivedfrom chromatin?
Match the description on the left with the correct term on the right When the nuclear membrane dissolves andy the chromosomes appear Options: When the nuclear membranes reform and visible chromosomes go back to less coiled Prophase chromatin Metaphase Chromosomes line up along the midline of the Telophase cell Anaphase When sister chromatids separate and move to opposite sides of the cell
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 the absence of Separase, how would this affect the chromosomes dynamic during mitosis? Explain in detail. *
