Imagine a haploid eukaryotic cell with a genome consisting of two unique chromosomes. The cell enters the cell cycle and divides by mitosis. Its daughters also enter the cell cycle and divide by mitosis to create granddaughter cells. 1) Draw the original cell in the G1 phase of the cell cycle as a circle with the chromosomes represented as double-stranded DNA molecules. 2) Below the first cell, draw all the daughter cells in G2 phase of their cell cycle using the same representation. 3) Below the daughter cells, draw all the granddaughter cells in G1 phase of their cell cycle. 4) Write the combined total number of chromatids that will be present in both daughters when they are at the beginning of M phase next to your picture of the daughter cells. 5) Could one or more of the granddaughter cells colzain an entire DNA strand that was present in the G1 phase of the cell that you drew for (1)? (Not a copy of the strand, but the actual molecule.) Write your one-word answer next to the granddaughter cells. 6) Highlight or label your diagram to justify your answer to (5).
