A housekeeping gene is typically a constitutive gene that is transcribed at a relatively constant level. The housekeeping gene's products are typically needed for maintenance of the cell.

WebIn molecular biology, a reporter gene (often simply reporter) is a gene that researchers attach to a regulatory sequence of another gene of interest in bacteria, cell culture, animals or plants.Such genes are called reporters because the characteristics they confer on organisms expressing them are easily identified and measured, or because they are … WebJun 14, 2024 · Heterochromatin Definition.
