A Speculative History of DNA: What If Oswald Avery Had Died in 1934?

abstract：:Polarized growth is maintained by both polarized exocytosis, which transports membrane components to specific locations on the cell cortex, and endocytosis, which retrieves these components before they can diffuse away. Despite functional links between these two transport pathways, they are generally considered to be ...

Proliferative stimuli generally also induce apoptosis, and anti-apoptotic factors are required to allow net cell proliferation.
