Psychological research has demonstrated that living in poverty has a wide range of negative effects on the physical and mental health and wellbeing of our nationâs children. Poverty impacts children within their various contexts at home, in school, and in their neighborhoods and communities.
Transformation. Definition. noun, plural: transformations. (1) The act, state or process of changing, such as in form or structure; the conversion from one form to another. (2) (biology) Any change in an organism that alters its general character and mode of life; post-natal biological transformation or metamorphosis. (3) (genetics) The genetic alteration of a bacterial cell resulting from the transfer of foreign DNA.
Transformation is one of three processes by which exogenous genetic material may be introduced into a bacterial cell, the other two being conjugation (transfer of genetic material between two bacterial cells in direct contact) and transduction (injection of foreign DNA by a bacteriophage virus into the host bacterium).NA material can be transferred between different strains of bacteria, in a process that is called horizontal gene transfer. Some species upon cell death release their DNA to be taken up by other cells, however transformation works best with DNA from closely related species.
