Bacteriophage muA temperate coliphage, in the genus Mu-like Viruses, family MYOVIRIDAE, composed of a linear, double-stranded molecule of DNA, which is able to insert itself randomly at any point on the host chromosome. It frequently causes a mutation by interrupting the continuity of the bacterial operon at the site of insertion.
FamilyA social group consisting of parents or parent substitutes and children.
MutationAny detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.
OperonIn bacteria, a group of metabolically related genes, with a common PROMOTER, whose transcription into a single polycistronic MESSENGER RNA is under the control of an OPERATOR REGION.
