Cell Differentiation & Specialization

●

Multicellular organisms have specialized cells

●

Specialized cells are different in structure and function

●

Cells become specialized during interphase of G0

●

The process in which a cell becomes specialized is called
Cell Differentiation

●

Stem Cells areNOT specialized yet

Specialized Animal Cells

Specialized Plant Cells

* Process by which a gene produces its product and the
product carries out its function.

Describe the relationship between:

GENES AND PROTEINS

A gene is a segment of DNA

that codes for a particularprotein.

*Some genes are:

1. expressed at all times

2. expressed in certain environmental conditions.

3. expressed at particular times.

4. expressed only in certain kinds of cells.

Gene Expression is a REGULATED process!
