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.
Because the term transformation had another sense in animal cell biology (a genetic change allowing long-term propagation in culture, or acquisition of properties typical of cancer cells), the term transfection acquired, for animal cells, its present meaning of a change in cell properties caused by introduction of DNA.
