Long description

The figure consists of two panels labelled (a) and (b). Both are screenshots taken from the digital fluorescence microscope (DFM) after using the measure line tool. The fluorescence micrographs show the same nucleus in light blue. It contains a yellow cross graticule. In (a) the measure line was used to measure the length of the nucleus. The red line is 18.67 micrometres long. The value is written in a light grey box that is placed across the line. In (b) the measure line was used to measure the width of the nucleus. The red line is 12.40 micrometres long. The value is written in a light grey box that is placed across the line. The scale bar in the images indicates 10 micrometres.
