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?

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?

What are the advantages and disadvantages of using insertion alleles versus alleles generated by chemicals (as in TILLING) in reverse genetic studies?

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.

Explain the following processes involving chromosome mutations and cancer development.

How the chromosome mutation producing the Philadelphia chromosome leads to CML.

Explain the following processes involving chromosome mutations and cancer development.

How the chromosome mutation producing Burkitt lymphoma generates the disease.

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?
