An electron is in its lowest energy state Option A: on the orbit closest to the nucleus.
In terms of genomics, a nucleus is the organelle within a cell that is membrane-enclosed and houses the chromosomes. The nuclear membrane has a variety of pores that enable the selective passage of specific molecules (such proteins and nucleic acids) into and out of the nucleus.
The nucleus carries the genes, structures that hold the genetic information, and controls and regulates the functions of the cell (such as growth and metabolism). Small structures called nucleoli are frequently detected inside the nucleus. The nucleoplasm is the gel-like matrix in which the nuclear parts are suspended.
