And when it reaches the first aug that is closer to the five N, it attaches onto that and initiates the process of protein synthesis. Now, how exactly do we terminate this process of translation? Well, there are these proteins, these enzymes known as release factors. And these release factors, they essentially move along the mRNA molecule and they bind to these special stop codons. And remember when we discussed genetic code, we said there are three different stop codons. We have UAAG, UAG and UGA.
