Question

genetic code
quiz complete

if the same base pairs are used to code for all organisms, why is there so much variation among organisms?
the order of the codons differs between organisms.
the order of the codons is the same between organisms.
the codons in each organism are the same.
the codons in each organism differ.

Explanation:

The genetic code is universal, meaning the same codons code for the same amino acids in most organisms. However, the order of these codons (which is determined by the order of base - pairs in DNA) varies. This variation in the order of codons leads to different sequences of amino acids in proteins. Different proteins have different functions, which in turn lead to the vast variation among organisms.

Answer:

The order of the codons differs between organisms.
