The following links will provide you with access to recently published research and review articles and popular press coverage focusing on the genetic concepts covered in this chapter.

• Read about the mutagenic effects of UV radiation in UV Damage Revisited and Correcting Sun Damage the Biotech Way, two articles by the author of Human Genetics.

The following sites will provide you with real-life cases and/or opinion articles focusing on the genetic concepts covered in each chapter. Read each case/article, consider the dilemma outlined, formulate your own opinions, and then discuss your views with your classmates, friends, family, and/or instructor. Several of the sites listed below will provide you with the opportunity to read the responses of other "web surfers" and to share your opinions in a "global conversation."

• Consider the possible outcomes of genetic susceptibility testing for Alzheimer disease with a case from the GenEthics Consortium.

The following sites provide you with tutorials, information-gathering opportunities, and/or interactive exercises focusing on the concepts covered in each chapter.

• MIT Biology Hypertextbook: Review mutations by studying this section of the MIT Biology Hypertextbook.

• What were the genetic effects of radiation in the offspring of atomic bomb survivors? Find out by examining this report from the Radiation Effects Research Foundation.

• You can easily access specific information Gaucher disease, Marfan syndrome, myotonic dystrophy, and polycystic kidney disease through the Human Gene Map Site.

• Online Mendelian Inheritance in Man is a searchable database of information on genetic diseases. Try searching for information about sickle cell anemia, fradile-X syndrome, Ehlers-Danlos syndrome, muscular dystrophy, and/or Huntington disease.

• The National Center for Biotechnology Information site provides you with the tools needed for "data mining" on the web. At this site, you can compare gene and protein sequences using BLAST, explore the outline of the complete human genome sequence using GeneMap'99, compare DNA from human and mouse sources using Human-Mouse Homology Maps, and obtain human, rat, and mouse gene sequence information using LocusLink. Other resources are also available at this site, so don't be afraid to explore!
