Most of the proteins in a typical eukaryotic cell are synthesized in the cytoplasm and the Rough Endoplasmic Reticulum (RER).

Here's a step-by-step explanation:

1. The process begins in the nucleus where the DNA is transcribed into mRNA.
2. This mRNA then leaves the nucleus and enters the cytoplasm.
3. In the cytoplasm, ribosomes (which are present in large numbers) attach to the mRNA. These ribosomes can either float freely or be attached to the RER.
4. The ribosomes translate the mRNA into a polypeptide chain, which is the primary structure of a protein. This process is called translation.
5. If the ribosomes are attached to the RER, the newly formed polypeptide chain enters the RER where it undergoes further modifications and folding to become a functional protein.
6. The proteins synthesized in the RER are usually those that are secreted out of the cell or are part of the cell membrane.
7. Proteins synthesized by free ribosomes in the cytoplasm usually stay within the cell and perform various functions.

So, the majority of protein synthesis occurs in the cytoplasm and the RER.
