What was robert brown looking at through a microscope when he found evidence of the 1827 scientific concept named in his honor?

Robert Brown was looking at a CELL NUCLEUS through a microscope.

Robert Brown (1773-1858) was a Scottish botanist. Studying the cells of plants, he called the ovals inside those cells the "nucleus" as he watched the interaction of pollen with the cell nucleus. The small, random oscillations of particles in the fluid of the cell are given the name "Brownian motion" based on the sort of fluctuating movement that Brown observed.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
