An alien visits Earth and is found to have the same 'genetic code' as humans. However, the alien has many more 'stop' codom which replace codoes that are redandant in the human genetic code. If nucleotide substitution errors occur at the same rate for aliens and humans, the aliens would have many more of whichkind of mutations? a.) missense mutation only b.) silent mutations only c.) nonsense mutations only d.) antisense mutations only e.) silent and missence mutations

A mutation arises in a bacterium that confers antibiotic resistance. Is this mutation harmful, beneficial, or neutral?
What type of mutation is shown in the diagram? Why do you think this type of mutation is referred to by this term?
A mutant strain of bacteria is isolated in which the amino acid glutamine is often erroneously substituted for glutamic acid during protein synthesis. What kind of mutation might be underlying this defect? How could you test this hypothesis?
In Experiment I, you established that beneficial mutations are rare. In Experiment II, you showed that the environment does not affect the probability of a beneficial mutation occurring. Knowing this, why then are mutations responsible for antibiotic resistance in bacteria so common?
Why is it more likely that insertions or deletions will be more detrimental to a cell than point mutations?
As we described in class, in the early 1960's Francis Crick and colleagues set out to determine how many nucleotide bases make up a codon, before it was possible to sequence DNA and before Nirenberg and his colleagues solved the genetic code. To do this, they used a chemical mutagen that they knew made single nucleotide changes, used this mutagen to conduct a screen for mutations that disrupted a particular gene, and collected a number of different mutations in this gene. Briefly describe the logic they used to deduce that the codon length is 3 nucleotides long.
Why are mutations bad and at the same time good?
What would be the most likely effect of a mutation at the following locations in an E. coli gene? a. -8 b. -35 c. -20 d. Start site
If I clone a complete eukaryotic gene, including the eukaryotic promoter region, ligate it into a plasmid, and transform it into E. coli, will I be able use the transformed E. coli to make the corresponding protein? Explain why, or why not? If you decide to do this, what would your cloning strategy be?

Two types of mutations discussed in this chapter are (1) nucleotide changes and (2) unstable genome regions that undergo dynamic changes. Describe each type of mutation.
Researchers sometimes use gamma rays to induce deletion mutations in certain organisms and thus create mutant strains. What might this suggest regarding how exactly gamma rays interact with DNA? What are they probably causing to happen that results in these deletion mutations?
