Here are parts of the DNA base sequences for 7 organisms:



Organism 3:

Organism 4:

Organism 5:

Organism 6:

Organism 7:

The question is: Which of the sequences is least likely to lead to a functional part of a protein, and why?

I researched stop codons in DNA and found them to be TAG, TAA and TGA - which doesn't help as pretty much all of the sequences feature one of these at least once.

Any help would be appreciated, thanks!
