Each characteristic is encoded by a pair of chromosomes. How does our body decide which of the DNA molecules to transcribe into RNA?
In: Biology
Feedback is the phenomenon that allows complex, potentially Turing complete behavior to arise from a system. It is achieved when the output of a system acts as an input and changes the new outputs.
The DNA produces RNA, the RNA moves to the ribosomes and creates proteins. Some proteins (histones and neucleosomes) act as spools and wind up sections of DNA, keeping them protected and temporarily unable to be used. Some proteins (helicases) cause sections of.the DNA to unzip, preparing them for transcription. There are plenty of other interactions as well.
The DNA ultimately produces the proteins. And the proteins ultimately control what the DNA does. And thus we have feedback. And from feedback we can get complex behavior.
