The Cell Cycle

Gene expression is the process in which  DNA is involved in the  process in which cells become  specialized for a particular  function.

Explanation:

The cells in the embryo undergoing many divisions goes on to form specialised structures in cell differentiation.

The cell differentiation is controlled at the gene level by the process of gene expression.

Gene expression provides the signal to the differentiating cell via signal transduction pathways.

The signals decides the fete of the specialized cells and functional protein formation.

Gene expression is mainly responsible for the control of process of transcription to occur by either using repressor  or promotors.

The processing of mRNA as splicing is the major function of gene expression so that correct gene coding is formed as required by the cell.

it's unlikely a majority of a large population would agree on issues

hope this : )
