Ribosomes chemical reactions

Webb8 apr. 2024 · Biology. It is a strong hypothesis that mitochondria and chloroplasts were prokaryotes that associated to primitive eukaryotic cells under mutualism (gaining protection and offering energy). This explains why within those organelles there are DNA and protein synthesis machinery, including ribosomes. This hypothesis is known as the … WebbThe ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain). Then, once translation is finished, the two pieces come apart again and can be reused. Overall, the ribosome is about one-third protein and two … Ribosomes are the structures where polypeptides (proteins) are built. They …
