Problem Set 3 and 4 1. Assuming that the one gene, one polypeptide hypothesis is correct, why is it that the proteome of a unique cell is not necessarily representative of the number of unique genes in that species? 2. What features of the nucleotide sequence can be used to identify active genes within genomic DNA? 3. What are some disadvantages to the presence of noncoding repetitive sequences in an organism’s genome? Could there be an advantage to having these regions in the genome? 4. In a given cell type, how can the number of genes being expressed be measured? What have been the conclusions of such analyses regarding the number and types of genes being expressed
