This article is part of a series involving chick embryo retina. Findings here suggest that protein molecules known as TOP are involved in the dividing of cells that gives rise to retinal cells. The working hypothesis of the article is that the TOP gene or genes influence the location of the accumulation of TOP. Furthermore, results suggest that after division the cell progeny inherit the parental ability to express the TOP gene--significant because it implies cellular memory.
