The organelles where protein synthesis takes place in a cell are called ribosomes. Here's a step-by-step explanation:

1. DNA Transcription: The first step in protein synthesis is the transcription of DNA into RNA. This process takes place in the nucleus of the cell. The DNA's double helix structure unwinds and one strand is used as a template to form an RNA molecule.

2. RNA Processing: The RNA molecule, known as pre-mRNA at this stage, undergoes a process called splicing where introns (non-coding regions) are removed and exons (coding regions) are joined together to form the mature mRNA.

3. mRNA Transportation: The mature mRNA molecule then leaves the nucleus and enters the cytoplasm of the cell.

4. Translation: The mRNA molecule is then read by the ribosome, the organelle where protein synthesis takes place. The ribosome translates the mRNA sequence into a chain of amino acids, which will fold into a functional protein.

5. Protein Folding: The chain of amino acids folds into a specific three-dimensional shape to form a protein. This process can occur spontaneously or be assisted by other proteins known as chaperones.

6. Post-Translational Modifications: After the protein is formed, it may undergo further modifications such as phosphorylation, glycosylation, or ubiquitination, which can affect the protein's function, location, or lifespan.

So, in summary, the organelles where protein synthesis takes place in a cell are the ribosomes.
