As you know, everything that starts must come to an end. This is the final stage called termination where this mRNA that has a stop codon, and calls a tRNA called a release factor. Therefore the whole production falls apart back to its state before the translation in the cytoplasm. When they do, the amino acids still hold together and create a polypeptide.

Welcome to ProteinCamel Channel and today your superstar is going to talk about the finishing touch, translation. Right now, our mRNA is on its way to the ribosome, let's take a look!
Ribosome made from rRNA and has three active sites. A site, P site, and E site. They collect the amino acids. Also has a small sub-unit, this is the large sub-unit.
tRNA has a special anticodon that will be joining the codon from the mRNA given in the ribosome and holds specific amino acids
This is our small sub-unit of the ribosome.
Now, once the mRNA goes inside the ribosome, those codons will indicate which tRNA is needed. Each tRNA has a special amino acid attached to the end to give it's amino acids
Initiation starts only when the mRNA has a start codon (AUG), then the small sub unit ribosome joins in which the big sub unit ribosome joins to have access to the active sites.

Now, in elongation, the ribosome (santa) moves one unit to the other codon, as a polypeptide (multiple amino acids) build in the P site and the cycle contiues as a new tRNA with a new amino acid to add on the chain

Well that's all folks! Ill see you next week on ProteinCamel Channel where we will be talking about naming proteins! Bye!
Met
Each protein have their own sets of uses, finding so many proteins, I bet there has definitely been a name for this protein
