How DNA Produces Traits

• DNA contains short segments called genes.

• The sequence (arrangement) of the nitrogen bases in the gene control the production of a protein.

Feb 26­4:26 PM

Proteins control the trait,or characteristics of an organism.

Steps of DNA replication

1. Enzyme "unzips" the DNA molecule.2. The strands separate and act as a "template" (model) for forming new strands.

Feb 26­4:14 PM

3. Free nucleotides are attached to the two strands.

4. Two NEW strands of DNA are created.

5. Each is one half original, one half new.
