Lesson 3: Expression Changes With Cell Type

< Previous SectionNext Section >

Different cell types express a distinct set of mRNAs from their genomes. For example, while a muscle cell (myocyte) and an immune cell (lymphocyte) both possess the same inherited genomic DNA, regulatory networks inside each cell type cause different subsets of these genes to be expressed as mRNA. And sometimes different cell types express the same mRNAs, but one cell type will produce more copies than the other.
