So the amino acid Is shown in purple as the circle. Our tRNA is shown in green. And this red region here is the start codon region. It's a sequence aug. Now, basically, once our ribosome complex has formed, there are three locations within a ribosome that we have to be aware of. We have the p side, we have the aside, and we have the east side. Now, we'll talk about the a side and east side in just a moment when we discuss the process of elongation.
