The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.Cell nucleus is the central unit of the cell, where it control activity of the cell. It contains genetic material which is called DNA. The genetic material contains proteins, histones and chromosomes. The chromosomes in nucleus is called nuclear genome which is enclosed by the nuclear envelop. Nucleus found in eukaryotic cell such as animal and plant cells. The top journals are peer reviewed scholarly journals. These provide high quality, meticulously reviewed and rapid publication, to cater the insistent need of scientific community. These journals are indexed with all their citations noted. The top open access journals are indexed in MEDLINE, PUBMED, SCOPUS, COPERNICUS, CAS, EBSCO and ISI.Nucleus portals are enhanced content collections focusing on specific biological processes or techniques. Each Nucleus will contain unique elements, but all will incorporate a relevant selection of Cell Press content including reviews, primary articles, webinars, image galleries, and Cell Symposia information.
