Molecular and Cellular Biology (MCB) is dedicated to disseminating new findings and advancing new research that contributes to our knowledge of the molecular biology of eukaryotic cells. Examining both microbial and higher organisms, the journal showcases significant discoveries in cellular morphology and function, genome organization, regulation of genetic expression, morphogenesis, and somatic cell genetics. The journal also examines viral systems, publishing papers that emphasize their impact on the cell.

The scope of Molecular and Cellular Biology includes: Gene Expression; Chromosome Structure and namics; Signal Transduction; Intracellular Trafficking; Mammalian Genetic Models.

Twice monthly, with 6,000 pages allocated in 2011. Print ISSN: 0270-7306. Online ISSN: 1098-5549.
