Here's a breakdown of the process:
1. Transcription:
- DNA (deoxyribonucleic acid), which contains the genetic code for the protein, is used as a template to create a messenger RNA (mRNA) molecule.
- This occurs in the nucleus of the cell.
2. Translation:
- The mRNA molecule travels out of the nucleus to the ribosomes in the cytoplasm.
- Ribosomes read the mRNA code and use it to assemble amino acids into a specific sequence, forming a polypeptide chain.
- This chain then folds into a complex 3D structure, becoming a functional protein.
So, protein synthesis encompasses both transcription and translation, where the genetic information is transferred from DNA to RNA and then used to build a protein.
