What is the spatial relationship between a repressor binding site and a promoter? How is this different from the spatial relationship between an activator binding site (or enhancer) and a promoter? What properties of DNA allow this difference?

What is love chemically? How can we define love with regard to the chemical processes concurrent with it?

cormorant35 asked:


What happens chemically when we fall in love? What are the chemical instigators and/or results of love particularly in brain and generally in body? What are the neuro-biological changes caused by love? Is love the result or the cause of such effects? Is there a satisfactory scientific answer to this “chicken or egg the first” kind of dilemma? Can we master the processes caused by love or are we helpless against them? I have fallen in love recently and there are incredible changes in my sleep cycle and many other biological rhythyms.Are we the unsuspecting victims of evolution/nature when we fall in love or do we consciously choose to fall in love? Are we the masters or the puppets?
