Open Question

What is functional genomics? How does it differ from comparative genomics?

Open Question

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

Open Question

Sequencing the human genome, the development of microarray technology, and personal genomics promise to improve our understanding of normal and abnormal cell behavior. How are these approaches dramatically changing our understanding and treatment of complex diseases such as cancer?

Open Question

What functional information about a genome can be determined through applications of chromatin immunoprecipitation (ChIP)?

Open Question

Translational fusions between a protein of interest and a reporter protein are used to determine the subcellular location of proteins in vivo. However, fusion to a reporter protein sometimes renders the protein of interest nonfunctional because the addition of the reporter protein interferes with proper protein folding, enzymatic activity, or protein–protein interactions. You have constructed a fusion between your protein of interest and a reporter gene. How will you show that the fusion protein retains its normal biological function?

Open Question

It can be said that modern biology is experiencing an 'omics' revolution. What does this mean? Explain your answer.

Open Question

How would you perform a genetic screen to identify genes directing Drosophila wing development? Once you have a collection of wing-development mutants, how would you analyze your mutagenesis to learn how many genes are represented and how many alleles of each gene? How would you discover whether the genes act in the same or different pathways, and if in the same pathway, how do you discover the order in which they act? How would you clone the genes?
