1. Describe how the 43 S preinitiation complex forms forEukaryotic protein synthesis.
2. How might the fact that mature mRNA having 3' poly A tails beused to isolate mature mRNA form eukaryotic genes.
3. The base analog 5-bromouracil is a thymine analog that causestransition mutations because it can easily interconvert between theketo and enol forms. Draw the base pair for 5-bromouracil andadenosine (keto) and 5-bromouracil and Guanosine (enol).
