Protein synthesis is carried out by two cell structures: the ribosome and the endoplasmic reticulum.
What is Protein Synthesis?
- Protein synthesis is the process through which cells manufacture proteins.
- The two steps are transcription and translation.
- Transcription is the process of genetic instructions being transferred from DNA to mRNA in the nucleus.
- The three steps are initiation, elongation, and termination.
- Once the mRNA is digested, the instructions are delivered to a ribosome in the cytoplasm.
- Translation takes place on the ribosome, which is made up of rRNA and proteins.
Endoplasmic reticulum:
- The endoplasmic reticulum serves as a transportation system for eukaryotic cells, as well as a myriad of other functions such as protein folding.
- This type of organelle is made up of two subunits: rough endoplasmic reticulum and smooth endoplasmic reticulum.
Ribosome:
- Ribosomes, also known as Palade granules, are macromolecular machinery in all cells that carry out biological protein synthesis.
- Ribosomes join amino acids together in the order indicated by the codons of messenger RNA molecules to form polypeptide chains.
