Molecular biology is the branch of biology that concerns the molecular basis of biological activity in and between cells, including molecular synthesis, modification, mechanisms, and interactions. The central dogma of molecular biology describes the process in which DNA is transcribed into RNA then translated into protein. Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life. Focusing on the cell permits a detailed understanding of the tissues and organisms that cells compose. Review journals are the evaluation of work by one or more people with similar competences as the producers of the work (peers). It functions as a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are used to maintain quality standards, improve performance, and provide credibility.
Evolutionary biology is a sub-domain of biology that studies the evolutionary processes (natural selection, common offspring, speciation) that have produced the diversity of life on Earth. In the 1930s, the discipline of evolutionary biology emerged from what Julian Huxley called modern understanding of synthesis, from biological research of unrelated areas, such as systematic genetics and paleontology. The field of investigation has been expanded to include genetic architecture of adaptation, molecular evolution and the different forces that contribute to evolution, such as sexual selection, geni drift biogeography. Furthermore, Some scientific journals specialize in evolutionary biology as a whole, notably evolutionary journals, Journal of Evolutionary Biology and BMC Evolutionary Biology. Some journals cover subspecialties of evolutionary biology, such as the Journals Systematic Biology, Molecular Biology and Evolution and its sister journal Genome Biology and Evolution, and Cladistics.
