Document Summary
Describes the way in which groups of transcription regulators work together to regulate the expression of a single gene. Process by which cell undergoes a progressive coordinated change to a more specialized cell type brought about by large scale changes in gene expression. Enzymatic addition of methyl groups to cytosine bases in dna; this covalent modification general turns off genes by attracting proteins that block gene expression. Transmission of a heritable pattern of gene expression from one cell to its progeny that does not involve altering the nucleotide sequence of the dna. Class of rna molecule that acts at a short range on adjacent cells. Small noncoding rna that controls gene expression by base paring with a specific mrna to regulate its stability and its translation. Important form of regulation in which the end product of a reaction or pathway stimulates continued activity; controls a variety of biological processes, including enzyme activity, cell signaling, and gene expression.
