ribosome

• Organite présent dans le cytoplasme des cellules vivantes, qui se lie à l'ARN messager et se déplace le long de celui-ci codon par codon, assurant l'assemblage des acides aminés en une molécule de protéine jusqu'à l'atteinte d'un codon stop, après quoi il se dissocie et libère la protéine finie pour l'usage de la cellule.

An organelle in the cytoplasm of a living cell that attaches to mRNA and moves along it one codon at a time, facilitating the assembly of amino acids into a protein molecule until a stop codon is reached, at which point it disassembles and releases the completed protein for cellular use.

   A complex molecular machine found within all living cells that serves as the site of biological protein synthesis (translation). It reads messenger RNA (mRNA) sequences and assembles amino acids into polypeptide chains.

   Ribosome

   • Ribosomes attach to the mRNA strand and move along it, reading the genetic code.
   • The ribosome facilitates the binding of transfer RNA (tRNA) molecules carrying specific amino acids.
   • Once the ribosome reaches a stop codon on the mRNA, it disassembles and releases the newly formed protein.
