In molecular biology, SWI/SNF (SWItch/Sucrose Non-Fermentable), [1] [2] is a subfamily of ATP-dependent chromatin remodeling complexes, which is found in eukaryotes.In other words, it is a group of proteins that associate to remodel the way DNA is packaged.
The WI-38 cell line stemmed from earlier work by Hayflick growing human cell cultures. [2]In the early 1960s, Hayflick and his colleague Paul Moorhead at the Wistar Institute in Philadelphia, Pennsylvania discovered that when normal human cells were stored in a freezer, the cells remembered the doubling level at which they were stored and, when reconstituted, began to divide from that level to ...

A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family".
The Bcl-2 family is most notable for their regulation of apoptosis, a form of programmed cell death, at the mitochondrion. [2] The Bcl-2 family proteins consists of members that either promote or inhibit apoptosis, and control apoptosis by governing mitochondrial outer membrane permeabilization (MOMP), which is a key step in the intrinsic ...
The term sister group is used in phylogenetic analysis, however, only groups identified in the analysis are labeled as "sister groups".. An example is birds, whose commonly cited living sister group is the crocodiles, but that is true only when discussing extant organisms; [3] [4] when other, extinct groups are considered, the relationship between birds and crocodiles appears distant.
Alternatively, in Australia Under the Family Law Act 1975 (Cth), a "stepparent" in relation to a child is interpreted as a person who is not a parent of the child and is, or has been, married to or a de facto partner of a parent of the child, and treats, or at any time while married to or a de facto partner of the parent treated, the child as a ...
Phylogenetic nomenclature is a method of nomenclature for taxa in biology that uses phylogenetic definitions for taxon names as explained below. This contrasts with the traditional method , by which taxon names are defined by a type , which can be a specimen or a taxon of lower rank , and a description in words. [ 1 ]
