Control in a living cell

Postby lateralsuz on March 30th, 2019, 12:14 pm 

I was first drawn to this site by some topics, which I can no longer find, that seemed to ask about the nature of control in a living cell. It was a issue that niggled at my mind during my studies, and which has never been explained.

Cells do not have brains within them. Nor do they seem to have extensive neural networks that could act as a pseudo-brain.

Cells can also exist in isolation, so they do not need to be controlled by outside influences. Yet they are regularly seen to adapt to changing circumstances in appropriate ways.

As was pointed out in the other posts, there are many cellular functions such as adapting internal structures during the reproductive cycle, (while expanding or contracting); or DNA repair; which seem to go far beyond the inevitability of a chemical reaction.

Is anyone aware of factors that could explain what is observed?
(Sorry if this is covered by the other topics - but I can't find them)

Hi Lateralsuz - I was not sure what you mean by your question? Could you clarify?
