**[110] + *[110]* + [110]** => 3 x 2^20 = 3145728
Why did you use 2^20 rather than 20^2 in this and the
succeeding calculations?
A comment on the probability of obtaining a given sequence
of amino acids. The significance of this question
for the question of the origin of life is different from
its significance for biological variation. In
biological variation, a system for making proteins from
amino acids is presupposed. In questions of the origin
of life, no such system would be available. In this
situation, the probability of obtaining ANY
meaningful protein seems to be to be effectively zero.
Proteins simply do not arise de novo in nature.
