Question

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.

Answer 1

(A) - The order of the codons differs between organisms.

because the other person said so... and I took the test... yeah.

Answer 2

The correct option is this: THE ORDER OF THE CODON DIFFERS BETWEEN ORGANISMS.
Codon refers to a sequence of three DNA, which corresponds to a particular amino acid or a stop signal. The same base pair are present in all living organisms, but in each organism, the base pair are mixed in different orders, this results in variations in the living organisms that are formed.
