Does it have to do with something that involves cell/DNA formation, or other topics in biology/chemistry? Or is this based on coincidence?

Golden ratio is (√5+1)/2.
This number is special because it’s the most irrational number that exists.
A rational number could be expressed as p/q an irrational number could also be expressed as p/q to some degree of accuracy (take π and 22/7). Where p and q are relatively small.
However (√5+1)/2 cannot be easily expressed as small p/q.
I cannot easily type this but (√5+1)/2 is expressed at a continued fraction of 1+1/(1+1/(1+1/(1+1/…….)))). That corresponds to the smallest real number where the variability in the next term is extremely high.
