MOLECULAR BIOLOGY OF

DIFFERENTIATION

(2)

DEVELOPMENT

• Development is the process of progressive changes during an organism's take on

successive shapes that characterize its life cycle.

(3)

• The first stages of the development of a plant or animal are called embryos.

• Development process

• has two main components besides growth, cell growth and cell division:

differentiation and morphogenesis.

(4)

• Morphogenesis, differentiated to specific

tissue structure of the organization consists of formal training.

• In animals, besides the programmed death of some cells (apoptosis), cell movements are also very important in morphogenesis.

(5)

Differentiation

• Formation of cellular specificity.

• Determines the specific structure and function of a cell.
