A poly A tail is at the end of the transcript, not the start. This is a perfect example of the dangers of analogies because this one is completely incorrect. Poly A tails protect RNA from degradation. A ribosome will not bind to that part, it will bind to something within the 5' untranslated region on the other end of the genome) ribosome binding site, kozak consensus sequence, etc). If you bound to the poly A tail and slide "down," you'd just slide right off the end of the gene.
Definitely nothing wrong with trying to find things that look similar across fields and try and gain differentiated insights, it's certainly an admirable thing and an important part of making many discoveries. But a first principles understanding of the structure of DNA, what a 5' end and a 3' end is, and how transcription/translation works (all bio 101 type stuff) would provide a much better foundation to do that with. You don't need a degree in biology to know the basics, just like you don't need a degree in CS to know the basics, but it's worth learning the basics if you want to get an understanding of the field or work with it.
