Biology triplet code help me please?!Watch this thread
Can someone please explain why theres a triplet code, i mean it doesnt make sense because it says because it can code for 20 amino acids but how can it when it apparently makes 64 different combinations? I am so confused with this triplet code stuff someone please help me
Hope that helps!
3 permutations '1' or '2' or '3'
4^3 = 64
DNA is a base 4 system with 3 values.
64 is the potential codes you could make with such a system.
DNA only needs to have information for around 20, amino acids and like mentioned 'STOP' codons.
So in Reality a lot of this 'potential code' is recycled meaning 2 values for the same amino acid. This makes the code Degenerate.
Think of it like this you have 64 boxes but 20 varieties of toys some boxes can contain the same type of toy meaning balls in 4 boxes(Glycine has 4 triplet codes) or blocks in 2 different boxes (Tyrosine having 2 triplet codes). You can fill your 64 boxes without 64 different toy varieties.
Hope it helps.
