The bacterial strain Acinetobacter has been tested for its
adhesion properties. A sample of five measurements gave readings of
2.69, 5.76, 2.67, 1.62 and 4.12 dyne-cm2. Assume that the standard
deviation is known to be 0.66 dyne-cm2 and that the scientists are
interested in high adhesion (at least 2.5 dyne-cm2).
a) Should the alternative hypothesis be one-sided or two-sided? (5
points)
b) Test the hypothesis that the mean adhesion is 2.5 dyne-cm^2.
Please answer by working it out by hand. Thankyou!

In your laboratory, you are growing a bacterial strain that
develops a mutation so that its normal crescentin protein does not
function. You continue to culture this bacteria and it
develops a second mutation so that its normal MreB protein does not
function.
(1) What is the original cell shape, and the shape after the
first mutation? Explain your answers based on the function of the
cytoskeletal proteins. '
(2) What is the cell shape after the second
mutation? Explain your answers...

Your colleague has isolated a mutant bacterial strain and found
the dna 5x10^8 bp in length. she has asked you to do restriction
mapping. you start by determining the base composition of the
bacterium, and find that the bacteria consists of 24% Thymine and
26% Guanine. you plan on using the enzyme NOTI which recognizes the
sequence 5'-GCGGCCGC-3'
