there is the first base the second base and the third base. each contain uracil, adenine, cytosine, and guanine. which of the bases is least important and why???

The third. Codons have something called wobble base pairing, meaning that the third of the three codons can change and still code for the same protein. In general the third base is variable in comparison to the first two. Although for a codon to be functional it needs 3 bases!

U A C G Out of the four C and G pair together and A and T pair together but T is replaced by U at one point so I think that T or U would be least important in a codon because the start codon is AUG, and there are no T because it switches to a U but actually they are all important but if you have to pick go with T or U.

a codon codes for an amino acid. without all three bases you would not get the correct or even a real amino acid. They are all of equal importance.

I dont see how any one could be less importent than the other without all three there would be no life.
