WebMay 7, 2024 · Briefly, the ribosomes interact with other RNA molecules to make chains of amino acids called polypeptide chains, due to the peptide bond that forms between individual amino acids. Inside the ribosome, three sites participate in the translation process, the A, P, and E sites. WebDec 19, 2024 · As polymerases and ribosomes do their work, they go through a few different shape changes. These changes help make them move in the correct direction. For example, the ribosome changes shape quite a bit during translocation. Each time it adds a tRNA to the polypeptide chain, it rearranges. The image below shows just one part of the ribosome ...

WebJul 5, 2024 · A lysosome is basically a specialized vesicle that holds a variety of enzymes. Those proteins are packaged in a vesicle and sent to the Golgi apparatus. The Golgi then does its final work to create the digestive enzymes and pinches off a small, very specific vesicle. That vesicle is a lysosome. WebJul 18, 2024 · The synthesis of new polypeptides requires a coded sequence, enzymes, and messenger, ribosomal, and transfer ribonucleic acids (RNAs). Protein synthesis takes place within the nucleus and ribosomes of a cell and is regulated by DNA and RNA. Protein synthesis Protein Synthesis Steps Protein synthesis steps are twofold.
