- The microscope image above shows the human chromosomes from a white blood cell. To create the image, researchers put cells in culture under conditions that encourage the cells to divide. They bathed the cells in a hypotonic (low salt) solution, which caused the cells to swell until their plasma membrane burst open. They "squashed" the chromosomes to spread them out, and stained them with a dye to make them visible under the microscope. Human chromosomes are numbered from longest (1) to shortest (22) plus the sex chromosomes X and Y. In the image chromosome 1 is about 7 micrometers. Answer the following questions. 1) What word(s) in the description above indicates that the chromosomes are not from a cell undergoing meiosis? 2) Based on the size, shape and appearance of the chromosomes in the image, in what cell cycle stage was the cell that the chromosomes came from? How can you tell? 3) Does the image suggest that centromere sequences are always located in the middle of a…arrow_forwardFigure 5.8 Examples of changes that occur to chromosome structure?arrow_forwardWhat would be the best labels for both x and y axisarrow_forward
