Detailed explanation-1: -During gene expression RNA polymerase reads the DNA and creates a copy called mRNA. The mRNA is then used as a template by another organelle, called the ribosomes. Ribosomes read the genetic code in the mRNA and create proteins. Those proteins will ultimately change the function of the cell and help it differentiate.
Detailed explanation-2: -Cellular differentiation is often controlled by cell signaling. Many of the signal molecules that convey information from cell to cell during the control of cellular differentiation are called growth factors.
Detailed explanation-3: -Gene Expression Regulates Cell Differentiation.
Detailed explanation-4: -A gene is a segment of DNA that provides the code to construct a protein.
