[[File:Diagram human cell nucleus es svg.png|400px|right]]
The '''nucleus''' is the most conspicuous [[organelle]] found in a [[eukaryotic cell]]. It houses the cell's chromosomes and is the place where almost all [[DNA replication]] and [[RNA synthesis]] occur. The nucleus is spheroid in shape and separated from the cytoplasm by a membrane called the nuclear envelope. The nuclear envelope isolates and protects a cell's [[DNA]] from various molecules that could accidentally damage its structure or interfere with its processing. During processing, DNA is transcribed, or synthesized, into a special RNA, called [[mRNA]]. This mRNA is then transported out of the nucleus, where it is translated into a specific protein molecule. In prokaryotes, DNA processing takes place in the cytoplasm.[http://www.ncbi.nlm.nih.gov/About/primer/genetics_cell.html]
