A. nucleus - rough ER - golgi complex - plasma membrane
B. golgi complex - nucleus - rough ER - plasma membrane
C. Plasma membrane - golgi complex - rough ER - nucleus
D. nucleus - smooth ER - golgi complex - plasma membrane

Answer :

The correct order for the production and secretion of a protein -

A. nucleus - rough ER - golgi complex - plasma membrane

Proteins

are the complex molecules composed of polypeptides

  • The protein formation begins in the nucleus where the DNA (deoxy ribonucleic acid) is transcribed into the mRNA.
  • After transcription, the mRNA undergoes of translation in the ribosomes
  • it modifies with help of Rough endoplasmic reticulum
  • This newly formed protein is then transported by the rough endoplasmic reticulum (RER) to the Golgi apparatus inside a vesicle.
  • The Golgi apparatus packages these proteins and targets them in different parts of the cell.
  • Proteins targeted for plasma membrane get embedded within the bilipid layer.

The process of protein formation begins with the process of transcription and ends with the transport of the formed proteins.
