Dynamic gene expression

Professor James Eberwine explains that gene expression within a cell is dynamic - changing in various ways as a cell ages.

Gene expression within a cell is dynamic. At the birth of the cell you have certain levels of gene expression, as a cell ages you get different levels of gene expression. Various types of pharmacological behavioral disease-related in cells can change gene expression. It is those changes that underline again the physiology associated with the function that you’re looking at.
