Translation
טקסט Storyboard
- 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.
- Ala
- CGA
- A site
- GCU
- P site
- UAC
- AUG
- Met
- E site
- 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

- bye!
- AUG

- bye
- Cys
- Ala
- 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
