Describe the experimental details outlining how you would use microarray technology to determine which gene is responsible for draught resistance in a species of tree such as the white oak? 33 2. What is the difference between genomics and proteomics? Would you expect the genome for a cell to be larger or smaller than its proteome? Explain. 34, 35 3. With respect to knock-out technology, it has been said "If a protein's function is important, its knock-out will result in lethality. On the other hand, if it's very important its function will be duplicated by another protein, and there will be no obvious phenotype for the knock-out." Please explain this statement in your own words. 34, 35 4. How would you use knock-out and knock-in methodology to show that two genes have an added effect on a cellular process as opposed to the process being regulated by only one of them individually? 46-53 5. Would you expect the number of peroxisomes to be positively or negatively correlated with the number of mitochondria? Justify your answer in terms of the function of each or in the context of overall cellular functions.
