Method BB11 cell dimensions were determined using the confocal microscope measure function. Cell surface area and volume were calculated assuming that cells were prolate ellipsoidal spherical with a smooth cell surface.
Comments Value is average of virgin and generations 2, 4, and 6. Saccharomyces cerevisiae reproduces asexually by budding and as a consequence of this process both mother and daughter cell retain chitinous scar tissue at the point of cytokinesis. Daughter cells exhibit a frail structure known as the birth scar, while mother cells display a more persistent bud scar. Value was calculated as mean of birth scar diameters of cells that divided 0,2,4 & 6 times
