How can there be 64 codon combinations but only 20 possible amino acids?

The amino acids in a colon can be in multiple different orders, even those there’s twenty amino acids they can be rearranged and different amino acids can be in combination in a codon, hope this helps!

Study smarter, learn faster without working harder

I spent a lot of my class time in secondary school being bored and restless. I was NOT a model student. Sitting in a class was always so boring to me. Then I discovered fun ways of making the lessons interesting when I attended the Mind Olympics in Earls Court. The 'mind athletes' at this event learned how to use their brains like a musical instrument. Learning and memorising facts easily like picking up feathers. Ever since that time I have been learning many subjects and showing other students how to enjoy their subjects while find better ways to get the results they want.
