how many combinations of amino acids exist?

[mdlsfreak]

the number i have is from tripod...(ya i know)

the article states 10^130 power.

the reason i ask is im stating contradictions against the primordial soup theory.

logic= WAY TOO MANY AMINO ACID SEQUENCES TO RANDOMLY FORM...

thanks

There are 20 amino acids and therefore the combinations possible for a string of x length is x^20.
