It's time for another Image of the week! This week's image was brought to us by citizen scientists in Project Discovery, and specifically by Yadaryon who pointed out several nice examples of proteins localized to the rim of the nucleoli.

The nucleolus is an organelle within the nucleus of your cells. There may be one or more nucleoli in each nucleus, but they usually occur in small numbers. The primary job of the nucleoli is to assemble ribosomes which in turn make proteins within your cells...Read more
