tails signment 1 1. Cell Cycle: Draw the cell cycle using the hand drawn cell cycle from class noting the major processes for each step. 2. Explain figure 14.2 in Karp. Draw a curve similar to the one in figure 14.2 but with cells that have doubling time of 30 hours. 3. A growth curve of an asynchronous culture of cells was conducted and the following results were obtained: (1) 5% of the cells were forming typical metaphases. (2) After a pulse chase experiment with [H] thymidine, 20% of the cells were labeled, as detected by autoradiography. (3) When metaphase cells were checked for radioactivity, the first labeled chromosomes appeared 6 hours after the short [PH] thymidine pulse (4) Given that the doubling time of these cells is 30 hours, how long the different cell cycle phases (Mitosis. S-phase. G₁ and Go will take in hours? 4. 1. Mitosis Draw a cell with a chromosome number of 2n-4 and genotype of AaBb where each gene is on a different chromosome. Label each chromosome with its appropriate allele. Draw out all stages of MITOSIS with the relevant structures and chromosomes labeled
