The DNA of a deletion of alpha bacteriophage has a length of 15 micrometers instead of 17 micrometers? How many base pairs are missing from this mutant?
In a genomic analysis looking for a specific disease gene,one candidate gene was found to have a single-base-pairsubstitution resulting in a nonsynonymous amino acidchange. What would you have to check before concluding that you had identified the disease-causing gene?
Let’s suppose you make a transposon library of the cellulose-secreting bacterium Komagataeibacter xylinus, with the goal of finding mutants that produce higher than normal amounts of cellulose, which would be useful industrially. However, despite your best efforts you are unable to isolate any transposon mutants that make more cellulose than the wild-type strain.Why might this have failed? List as many reasons as you can think of.
