These structures protect and enclose gene expression products as they move from the site of protein synthesis to its final secretion from the cell.

The correct answer will be- Cargo vesicles

Explanation:

The product of the gene expression is known as the protein which is formed as the result of the transcription and translation.

The process of translation takes place in the ribosomes attached to the endoplasmic reticulum after which the proteins enter the lumen of the endoplasmic reticulum.

The protein then enters the secretory pathway which represents the movement of proteins by packaging them in cargo vesicles attached with the cargo proteins.

Thus, Cargo vesicles are the correct answer.
