Master Objectives:
3.3.B.b Recognize that DNA codes for proteins, which are expressed as the heritable characteristics of an organism. (DOK: 1)
3.3.B.e Identify possible external causes (e.g., heat, radiation, certain chemicals) and effects of DNA mutations (e.g., altered proteins which may affect chemical reactions and structural development). (DOK: 2)

DNA provides the CODE The sequence of nitrogen bases
in DNA code for the building of protein
The code (genes) are like a blueprint for constructing enzymes and cell parts

different protein productTuesday, March 9, 2010
