ribosome wikipedia - EAS
- A ribosome is a mixture of protein and RNA that starts being made in the nucleolus of a cell. The nucleolus is found in the center of the nucleus. The nucleus is protected by the nuclear envelope, and lets things out through the nuclear pores. The job of the ribosome is to make new proteins.

See all on Wikipediahttps://en.wikipedia.org/wiki/RibosomeRibosomes are macromolecular machines, found within all cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains. Ribosomes consist of two major … See more

Les ribosomes sont des complexes ribonucléoprotéiques (c'est-à-dire composés de protéines et d'ARN) présents dans les cellules eucaryotes et procaryotes. Extrêmement bien conservés au cours de l'évolution , ils ont pour fonction de synthétiser les protéines en décodant l'information contenue dans l'ARN messager. Ils sont constitués d'ARN ribosomiques, qui portent l'activité catalyti…
