Inactive gene
Webgenerally have a low gene density, but can also contain active genes (Gilbert et al. 2004). The ability of genes to be activated is not necessarily lost when chromatin is packed into more compact fibers. Conversely, inactive genes close to active genes in an open chromatin envi-ronment can stay inactive. In these cases, it is not the WebSo far, a number of histone variants have been found and localized to specific areas of chromatin. For instance, H2A.Z is a variant of H2A and is often enriched near relatively …

WebIn general, only one of the two X chromosomes carried by a female is active in any one cell while the other is rendered inactive. This is why when a female inherits a defective gene on one X chromosome, the normal gene on the other X chromosome can usually compensate.
WebMar 31, 2024 · When transiently transfected into monkey kidney (COS) cells or stably transfected into mouse L cells, a mutant that lacked all three introns was completely inactive. Constructs that contained intron 1, either alone or in combination with another intron, were expressed as efficiently as was the normal intact rpL32 gene. X-inactivation (also called Lyonization, after English geneticist Mary Lyon) is a process by which one of the copies of the X chromosome is inactivated in therian female mammals. The inactive X chromosome is silenced by being packaged into a transcriptionally inactive structure called heterochromatin. As nearly all female mammals have two X chromosomes, X-inactivation prevents them fro…
