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

Tuesday, March 9, 2010

DNA provides the CODE The sequence of nitrogen bases

in DNA code for the building of protein

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

Each strand of DNA contains many genes which each code for a

different protein productTuesday, March 9, 2010
