A nuclear family, elementary family or conjugal family is a family group consisting of two parents and their children. It is in contrast to a single-parent family, to the larger extended family, and to a family with more than two parents. Nuclear families typically center on a married couple; the nuclear family may have any number of children. There are differences in definition among observers; some definitions allow only biological children that are full-blood siblings, but others allow for a stepparent and any mix of dependent children including stepchildren and adopted children.
Nuclear membrane. A nuclear membrane, also known as the nucleolemma or karyotheca, is the lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. The nuclear membrane consists of two lipid bilayersâthe inner nuclear membrane, and the outer nuclear membrane. The space between the membranes is called the perinuclear space, a region contiguous with the lumen (inside) of the endoplasmic reticulum.
