From the source (click through to read more): "In this photograph, a labeled DNA segment (a known oncogene) has been put into a mouse oocyte, a cell that develops into a mature egg cell. The labeled DNA has paired with (or hybridized to) multiple copies of RNA in the mouse oocyte. The presence of this RNA (shown here as black dots inside the nucleus of the immature cell) shows that the normal cellular counterpart of the oncogene is active, suggesting that it is critical for normal germ cell development. Expression of genes is manifested by the production of RNA transcripts within cells."

Photographic Memory

Others are able to read through a page in a book and then recite the page from memory, or memorize hundreds of names and numbers from a telephone directory.
