The cell cycle , or cell division cycle , is the series of events that take place in a cell biology cell leading to its division and duplication replication . In cells without a nucleus prokaryotic , the cell cycle occurs via a process termed binary fission . In cells with a nucleus eukaryotes , the cell cycle can be divided in two periods interphase during which the cell grows, accumulating nutrients needed for mitosis and DNA replication duplicating its DNA and the mitosis M phase, during which the cell splits itself into two distinct cells, often called daughter cells and the final phase, cytokinesis, where the new cell is completely divided.

A cis regulatory element or cis element is a region of DNA or RNA that regulates the expression of genes located on that same molecule of DNA often a chromosome . This term is constructed from the Latin word cis , which means on the same side as . These cis regulatory elements are often binding sites for one or more trans acting factor s. A cis element may be located upstream of the coding sequence of the gene it controls in the promoter region or even further upstream , in an intron , or downstream of the gene s coding sequence, either in the untranslated or untranscribed region. See Promoter biology Identification of relative location promoter location for explanation of notation. An example of a cis acting regulatory sequence is the operator in the lac operon .
