Answer:

4 codons

Explanation:

In a DNA sequence, codons are in a set of 3 base pairs.

So, we can calculate the number of codons in the sequence by dividing the total number of base pairs by 3.

There are 12 base pairs in the sequence. Divide this by 3:

12/3

= 4

So, there are 4 codons in this sequence.
