Document Summary
So we painstakingly prepared our messenger rna last week, and now we are going to translate them into protein. I would suggest going back and re-watching the video and you try to explain what is going on using the proper terminology instead of listening to the narraion. So we have a mature messenger rna, its got a poly a tail, a 5" g cap, we have spliced it to get rid of the introns, and now its geing out of the nucleus through the nuclear pores. You are going to need to be able to read that messenger rna, and we read them 3 nucleoides at a ime. You have 4 possible nucleoides which gives us 64 possible triplet combinaions. We need one for the start codon, every singe coding region on mrna will all start with the same codon, aug, and it codes for methionine. Not all proteins begin with methionine when they are done.
