Relation entre ADN et protéines Notion de gène


Comment les protéines sont-elles synthétisées à partir de l'ADN?

L'ADN des chromosomes est localisé dans le noyau, séparé du cytoplasme par l'enveloppe nucléaire, alors que la synthèse des protéines s'effectue dans le cytoplasme. Pour cela, des copies du gène s'effectuent dans le noyau, sous forme d'ARN messager contenant la même information que le gène.

Où se trouve la synthèse des protéines ?

Localisation de la synthèse des protéines Des acides aminés radioactifs (par exemple de la leucine tritiée) sont ajoutés au milieu de culture de cellules eucaryotes. Un lot L est constitué de cellules dont le noyau a été détruit peu avant la mise en culture (elles sont énucléées).

Où se trouvent les gènes ?

Ils sont répartis dans les chromosomes qui se trouvent dans les noyaux, au cœur des cellules. Lorsque l'organisme a besoin d'une protéine pour exercer une réaction biochimique donnée, le gène correspondant est transcrit pour donner une copie du message génétique qui a pour support un ARN (acide ribonucléique).
