GENETIC DISORDERS Phenylketonuria (PKU)
Autosomal recessive genetic disorder characterized by a deficiency in the
enzyme hepatic phenylalanine hydroxylase (PAH
necessary to metabolize the amino acid phenylalanine to the amino acid tyrosine

IF ALL THE CELLS IN YOUR BODY HAVE THE SAME DNA, HOW ARE THEY DIFFERENT?
Each kind of cell (ex. Skin, nerve, muscle) uses only some of the genetic information it contains

A human liver cell and a human skin cell in thesame person have the same genetic sequences.However, these cells are different because theliver cell (1) has more dominant traits than the skin cell (2) can reproduce but the skin cell cannot (3) carries out respiration but the skin cell
does not (4) uses different genes than the skin cell

HUMAN GENOME PROJECTProject goals were to identify all the approximately 20,000-25,000
genes in human DNA determine the sequences of the 3 billion chemical
base pairs that make up human DNA store this information in databases improve tools for data analysis transfer related technologies to the private sector address the ethical, legal, and social issues (ELSI)
that may arise from the project.

13-year project coordinated by the U.S. Department of Energy and the National Institutes of Health
Completed in 2003 Wellcome Trust (U.K.) became a major
partner; additional contributions came from Japan, France, Germany, China, and others
