WebBiological assay is based on a measurable growth response from a test organism, as a result of the biological action of any compound. In many instances, this growth response will be an inhibition of elongation or a curvature of an organ such as a stem. The validity of biological assay procedures is based on two assumptions: (1) the plant ... WebThe main focus of my current research is the evaluation of genetic and epigenetic modifiers of cellular and tissue / organ response at low doses and low dose rates of ionising radiation. The candidate pathways involved in the biological response are being tested by using phenotypically different inbred mouse strains and genetically modified mouse models. …
