( b) What is the difference between apoptosis and necrosis? ( c) What are caspases and what is their function in the cell?
Cell division and apoptosis
a) The cell cycle is divided into different phases (named M, G0, G1, S and G2). Can you explain what happens during the different parts of the cycle and how to control it?
b) What is the difference between apoptosis and necrosis?
c) What are caspases and what is their function in the cell?

- -Mature parent cell Budding- cell 1 μη Test II. Examine the micrograph of the yeast cells. The scale bar under the photo is labeled 1 um. The scale bar works in the same way as a scale on a map, where, for example, 1 inch equals 1 mile. In this case the bar represents one thousandth of a millimeter. Using the scale bar as a basic unit, determine the diameter of the mature parent cell and the new cell. Start by measuring the scale bar and the diameter of each cell. The units you use are irrelevant, but working in millimeters is convenient. Divide each diameter by the length of the scale bar and then multiply by the scale bar's length value to give you the diameter in micrometers.arrow_forwardName the phases of the cell cycle. b) During which phases are the chromosomes and then the cytoplasm split, respectively? c) Describe one mechanism that is used to regulate the cell cycle.arrow_forwardWhich of the following diagrams correctly depicts the orientation of microtubules during metaphase of mitosis?
