Genomic sequencing has opened the door to numerous studies that help us understand the evolutionary forces shaping the genetic makeup of organisms. Using databases containing the sequences of 25 genomes, scientists examined the relationship between GC content and global amino acid composition [Kreil, D. P., and Ouzounis, C. A. (2001) Nucl. Acids Res. 29:1608–1615]. They found that it is possible to identify thermophilic species on the basis of their amino acid composition alone, which suggests that evolution in a hot environment selects for a certain whole organism amino acid composition. In what way might evolution in extreme environments influence genome and amino acid composition? How might evolution in extreme environments influence the interpretation of genome sequence data?

SDS-PAGE is a method used to separate proteins by which of the following characteristics?

How can proteomics identify differences between the number of protein-coding genes predicted for a genome and the number of proteins expressed by a genome?

How do high-throughput techniques such as computer-automated, next-generation sequencing, and mass spectrometry facilitate research in genomics and proteomics? Explain.

Based on the tree of life in the following figure (Figure 16.12), would you expect human proteins to be more similar to fungal proteins or to plant proteins? Would you expect plant proteins to be more similar to fungal proteins or to human proteins?

The CBF genes of Arabidopsis are induced by exposure of the plants to low temperature. Can you design a method that would reveal these changes in gene expression in a way that a farmer could recognize them by observing plants growing in the field?
