Homework Answers
RNA splicing in eukaryotes permits more than one protein product to be formed from a particular gene (or pre-mRNA of the gene). It is enabled by the spliceosome, a eukaryotic synapomorphy.
The RNA splicing permits the formation of multiple proteins by combining the exons after the removal of the introns from a single gene.

QUESTION 1 George Beadle and Edward Tatum performed an experiment in which they made single-gene mutations in the bread mold Neurospora crassa. These mutations resulted in several Neurospora auxotrophs. Further analysis revealed specifically how the mutations affected synthesis of the amino acid in question. What was the significance of these results? A single gene encodes a single protein, in the case of this experiment, an enzyme. Enzymes are needed to synthesize amino acids. They showed that mutations are heritable. They...

QUESTION 6 Assume you are studying a protein-coding gene, ACEX, which includes 4 exons as illustrated in the gene map below. The 5' UTR and 3' UTR segments are each 25 bp long. Exons 1 thru 4 are 100, 200, 300, 400 bp long, respectively. Each intron is 200 bp each. The locations of the relevant EcoRI sites within the ACEX locus are indicated, but the location of other restriction enzyme sites (like BamHI) are not shown." EcoRI probe EcoRI...
