These questions are to guide your studying. They do not cover all of the topics that may be on exams. This is the biosynthetic pathway for arginine synthesis in Neurospora: Explain why a Neurospora mutant strain that is defective in production of enzyme B would be able to grow on MM + citrulline or MM + arginine, but not MM + ornithine. Would the Neurospora strain described in the question above be able to grow on MM supplemented with all 20 amino acids? How about MM +glycine? What was the purpose of the X-rays in the Beadle and Tatum experiments? (Choose the correct answer.) A difference between prokaryotes and eukaryotes is: (a) mRNAs are spliced in prokaryotes. (b) genes in prokaryotes must all encode proteins. (c) In prokaryotes, RNA must be exported to the cytoplasm prior to translation. (d) transcription and translation are coupled in eukaryotes. (e) the transcript is usually not modified before translation in prokaryotes. Place the following in order of occurrence: (a) release of primary RNA transcript, (b) unwinding of the DNA, (c) RNA polymerase binds to promoter, (d) export of mRNA to the cytoplasm for translation, (e) Addition of 5' cap and polyA tail, (f) elongation step of transcription. The genetic code is 'degenerate.' What does this mean? How many possible amino acids could a genetic code of four bases specify, assuming at least one Start and one stop codon? Translate the following mRNA into a polypeptide. 5'-AAAUGCCGGUAUGGAAGUUCCACGAAGGACCUAUCACGGCAUAAAUACUA-3'
