• Illustrate the chromosome changes in interphase and mitosis using a diploid cell that is 2n=4 (tw large and two small chromosomes). Label the circles as G1 and G2 stages of interphase and each phase of mitosis (in order). Draw the chromosome in each circle using the following guidelines. 1) For unreplicated chromosome draw a line (/) and for replicated chromosome draw an X. 2) For simplicity, do not indicate that the chromosomes are decondensed chromatin during terphase. . 3) Skip drawing the nuclear membrane or spindle fibers, since we are focusing on the hromosomes. • Label genes in the resulting daughter cells as A/a and B/b.

Task: Show your work/explain your reasoning as much as possible. If a certain species has a DNA content of 12 picograms in each diploid cell's nucleus when the cell in in G1 of the cell cycle, what would be the expected DNA content (in picograms) of a triploid cell (from the same species) in mitotic prophase? Consider ploidy changes and/or chromosome form changes, if applicable, when explaining your reasoning.
describe the folded fiber model of the mitotic chromosome the folded fiber model is based on each_____ consisting of single fiber wound like a skein of yarn. Each fiber consists of ___-. A cloning process occurs during the transition of _____ chromatin into more condensed chromosomes during ____ of mitosis or meiosis. Such condensation leads to 5000 folded ____ in the length of the DNA. The transition is at the end of ______ and in the beginning of ____ when the chromosomes are in the condensation process. This eventually leads to typically short and fat and chromosome. interphase, RNA and protein, prophase, protein, DNA and protein, couple of fibers, contraction, extension, chromatid, metaphase

Please help Place the images of the cell division in the right order and label them a) What is the final product of this type of cell division? Indicate the number of dauahter cells, the TYPE OF CELLS (somatic cells? sex cells? other?), where in the body this process takes place, whether they are genetically diverse pridentical, haploid or diploid, the chromosome number in human cells, whether they contain sinale- or double-stranded chromosomes, and what the "fate" of these cells is i.e. what will they go on to do, if given the chance)?
Discuss Concepts One of the human chromosome pairs carries a gene that influences eye color. In an individual human, one chromosome of this pair has an allele of this gene that contributes to the formation of blue eyes. The other chromosome of the pair has an allele that contributes to brown eye color (other genes also influence eye color in humans). After meiosis in the cells of this individual, what fraction of the nuclei will carry the allele that contributes to blue eyes? To brown eyes?
1. Your class has been studying cell division in a number of organisms with different chromosome numbers. Unfortunately, the slides showing the different stages of mitosis and meiosis got mixed up, and some of them got lost. The figures below show the 12 slides that you have managed to find. The organism that you have been studying has a 2n number of 8 with one pair of large metacentric chromosomes, one pair of small metacentric chromosomes, one pair of acrocentric chromosomes and one pair of telocentric chromosomes. a. Do any of the recovered slides below show the stages of cell division indicated in the table in the answer sheet? If so, please write only the slide number in the correct place in the table on your answer sheet. b. Consider slide 6 above. What chromosomal event / phase of cell division is being shown here? c. What is wrong with the picture of this stage of cell division?

Q1. a. Manually, using a pencil, draw a cell in anaphase II from an organism in which 2n = 2 and each chromosome is metacentric. b. Given that each G1 nucleus from this organism contains 16 picograms of DNA, how many picograms of chromosomal DNA would you expect in the cell shown here?
In class, we talked about flow cytometry which allows scientists to determine what stage of the cell cycle cells are in by measuring their DNA content. Draw what the graph would look like for the mutant below at a 0-time point when there are 1000 cells total, with 5000 cells in G1, 350 cells in M and G2, and 150 cells in S phase. And then a graph of 1 hour later when the cells should have competed for mitosis: → loss of function of cdc25
