"We know specific genes are turned on in specific cells, but we don't know to what extent this happens"

Walter Gilbert's quote is describing the complexity of gene expression in cells. We know that particular genes are revealed in particular cells, but we don't understand the full extent of this expression. This suggests that we don't understand how much of a gene is expressed in a specific cell, or just how much of a gene is expressed in various cells. This is an important location of research study, as understanding gene expression can assist us much better comprehend how cells work and how illness develop. It can likewise help us develop treatments for diseases, as we can target specific genes in particular cells. Ultimately, understanding gene expression can assist us better comprehend the complexity of life.
