• Question: During gene translation, how does the correct tRNA molecule come to the ribosome? Is this all down to random collisions between tRNA molecules and the ribosomes?

      Good question, Sean. Sorry it’s taken me so long to reply. It’s been a bit of a hectic day.

      The correct tRNA will bind to the ribosome randomly- but as only the right tRNA will bind for the specific codon- that’s how it knows that it’s the right one, if that makes sense? Sorry it’s short but I’m in the middle of experiments- if you want more details or have more questions, feel free to ask! 😀
