Map 491 DNA Crossword

This template contains a combination effect of all 64 hexagrams three letter codons. None are missing but some can be a part of another. At no time can the same three letters appear in the same game. This has not beaten my personal best of 39 hexagram letters but I do continue to improve in the speed with which I can do the game. I shall keep trying.  I give below a blank template for you to try on. Good luck.

I have now managed to complete this game in 36 and as that number appears is so many ways throughout DNA maps I would hazard a guess that is going to be the smallest I get. I will amend if I manage to do it in less. x
