Go to the National Institute for Child Health and Human Development (http://www.nichd.nih.gov), locate the search box at the top right corner of the homepage, and enter 'RUSP' to search for information on the Recommended Uniform Screening Panel. From the options that appear, select 'Brief History of Newborn Screening' and locate the discussion listing the criteria for adding a disease to the RUSP list. What are the criteria for listing a disease on the RUSP list?

Using the data in Table B, calculate the average number of kilobase (kb) pairs per centimorgan in the six multicellular eukaryotic organisms. How would this information influence strategies to clone genes known only by a mutant phenotype in these organisms?

A tumor is a growing mass of abnormal cells. Describe the difference between a benign tumor and a malignant tumor.

For the retinal cancer retinoblastoma, the inheritance of one mutated copy of RB1 from one of the parents is often referred to as a mutation that produces a 'dominant predisposition to cancer.' This means that the first mutation does not produce cancer but makes it very likely that cancer will develop.

Explain why cancer is almost certain to develop with the inheritance of one mutated copy of RB1.

Discuss the similarities and differences between forward and reverse genetic approaches, and when you would choose to utilize each of the approaches.

What are community-based genetic screening programs? What is the intent of such screening programs? Why are members of specific communities or populations offered the chance to participate in such programs?

A tumor is a growing mass of abnormal cells. What must happen for a benign tumor to become malignant?
