Module 6 Project A: Stereo Payment
Calculator
You have just purchased a stereo system that cost $1,000 on the
following credit plan: no down payment, an interest rate of 18% per
year (and hence 1.5% per month), and monthly payments of $50.
The monthly payment of $50 is used to pay the interest and
whatever is left is used to pay part of the remaining debt.
Debt0= 1000
Interestn = Debtn*0.015
Principaln = 50 - Interestn
Debtn+1 = Debtn -...
Suppose you want to isolate viruses that infect marine
cyanobacteria. Describe how you would do that compared to using the
kinds of agar plates you were exposed to in this first laboratory
session. Describe what parts of the procedure specifically must be
changed. Would you need to consider incubation temperature
differently? What kind of medium would you use to grow your
cyanobacteria and phages?
1. How would one isolate and culture Pseudomonads
putida from soil sample contaminated with hydrocarbons
2. Describe two physical properties that will enable
one to isolate TOL plasmid from the chromosomal DNA of a
bacteria.
3. Describe a method to restrict or digest the TOL
plasmid.
4. Explain two methods to be used to increase the
ligation efficiency of restriction products with blunt ends.
5. How can one ascertain if one's restriction
digestion is successful.
You would like to isolate a mutant fern capable of
growing in the presence of cadmium, which is toxic to wild type
ferns. What specific part of a fern plant would you treat with a
mutagen called EMS in order to be able to identify mutant ferns
within the same generation? Explain your strategy, which should be
able to identify mutations right away (even if the mutation is
recessive). Hint: Look at the life cycle of the fern
So in...
You wish to isolate the acetal from acetophenone and methanol
explain why one of the following organic acids is the best choice
to catalyze the reaction: a) p-toluenesulfonic b) trifluoroacetic
acid c) hydrochloric acid?
You have an enatiomeric excess of 2% and have more R than S
isomer. How much R isomer do you have?
What equation is needed for this problem? How do you solve it?
