Masonic signature in SARS-CoV-2 genome

Check out the genome at the link below. Go to the very bottom of the page. There are exactly 33 adenines at the very end of the genome. This is the 3'-UTR section of the RNA which is an untranslated region marking the end of transcription. It serves no practical purpose so quite easy to insert a signature there. Interesting.
