Detailed explanation-1: -Most of the specialized cells in a multicellular organism are capable of altering their patterns of gene expression in response to extracellular cues.
Detailed explanation-2: -Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA. The set of genes expressed in a cell determines the set of proteins and functional RNAs it contains, giving it its unique properties.
Detailed explanation-3: -The genes which are expressed in all cell types and almost all the time. These genes are called housekeeping genes.
Detailed explanation-4: -Specialized cells regulate the expression of genes because they? Do not need the proteins that are specified by certain genes.
