Explanation:

Gene expression is the process by which information from a gene is used in the synthesis of a functional gene - product, which is mainly proteins. It controls the types and amounts of proteins made in a particular cell. Rearranging DNA to make new genes is not gene - expression. DNA duplication prior to cell division is part of the cell - cycle process and not gene expression. Removal of introns is a part of RNA processing during gene expression but does not fully define gene expression.

Answer:

Control of the types and amounts of proteins made in a particular cell
