Hey, I was wondering if it was safe to say that the ribosome reads the mRNA codons in a 5′-3′ direction. If that’s the case, can I assume that the tRNA is complementary, with it’s 3′ end “corresponding” to the N-terminus of the aa that it is carrying and it’s 5′ end corresponding to the C-terminus? I’d really appreciate the help!
Binding an amino acid at 3′ end of tRNA captures 2 high energy bonds of an ATP molecule that will then be released during a peptide bond formation. This stuff doesn’t happen magically on its own.

there are A LOT of things in this video that were believed to be true like 15 years ago… but they are not

I thought the ribosome moved down the mRNA, not the mRNA moving through the ribosome?

I think that only Prokariota own E-site. That may be the explanation.

That’s the exit site that they forgot about it. LOL. It’s not that important though.

In simple terms, before the tRNA leave the ribosome they are bound to the E site

what is the purpose of the E site?

hmm… what about the E-site?

there are 3 binding sites for the tRNA on the ribosome,
the third is known as the E site.
