WebThis rules out the conservative replication model, which predicts that both heavy density DNA and light density DNA will be present, but none of intermediate density will be present. This result is consistent with the semiconservative replication model, which predicts that all DNA molecules will consist of one 15N-labeled DNA strand and one 14N ...

WebThis hypothesis was strengthened by the experiment of Meselson and Stahl in which they elucidated the nature of replication of DNA. The cell was first discovered to be dividing by Hugo Von Mohl in 1835. Later, cell division was filmed and captured by Kurt Michel in 1943, who was renowned for micro-cinematography.
