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.
For the following five sequences, what is the consensus sequence?
5′–GGGAGCG–3′ 5′–GAGAGCG–3′ 5′–GAGTGCG–3′ 5′–GAGAACG–3′ 5′–GAGAGCA–3′
a. 5′–GGGAGCG–3′
b. 5′–GAGAGCG–3′
c. 5′–GAGTGCG–3′
d. 5′–GAGAACG–3′
In the procedure shown, why was it necessary to link thecoding sequence for the A or B chains to the sequence forβ-galactosidase? How were the A or B chains separated fromβ-galactosidase after the fusion protein was synthesized in E. coli?
