I should have provided more detail.
This has to do with nucleotide strings in DNA.
for example, consider the follow string:
123 456 789
act gta ccc ... (spaces not in string, just for clarity)
Any start position must begin at position 1,4,7, etc.
Any end position must conclude at position 3,6,9 etc.
So, I am not sure the function below would do exactly what I need??
