In this article we will discuss about the replication of eukaryotic chromosome. Taylor in 1958 used radioactive thymidine (3H-thymidine) to label Viciafaba root tip chromosomes. He showed that the chromosomes replicated in a semiconservative manner, and proposed that each chromatid was made up of a single DNA molecule. Thus each sister chromatid is composed of one of the two progeny [...]

Whatever "knowledge" he could gather, he transferred it to his progeny/off-spring, and thus there was an accumulation of "knowledge" about various things.

But he, in fact, observed only the walls of actual cells as he was viewing dead cells. Subsequently, [...]
