DNA Codons and how they can become very different depending on certain factors

 

Here we have the four colours or letters of DNA...........but note it is not just GACT as both letters can be pointing upwards and downwards............it may mean nothing but its a fact worth noting incase it is required in the future. 

It takes a minimum of 36 triangles to create a pattern that contains ALL 64 codons of DNA as you can read them in any direction. TGC would also be CGT. I believe the North South orientation is most likely but you can set up a map with an East West orientation too. 

So there are many reasons something we think we know may well play out differently. There are only 20 amino acids so more than one codon can make that amino acid but what are their differences there can be many.
