This is because 37 degree celsius is an optimum temperature for the working of restriction enzymes.
These enzymes are isolated from bacteria which live under normal climatic conditions. Under these conditions, the enzymes present in this bacteria will work to their maximum potential. Also the temperature they live in around 30 to 35 degree celsius.
Therefore we perform restriction digestion at 37 degree Celsius so that it can work efficiently at this optimum temperature.
Please rate.
Hypothesize about why restriction enzyme digestions are performed at 37 degrees Celcius.
The pH of blood is 7.40 at 37 degrees celcius. If the Kw is 2.4x10^-14 at rhis temperature, what is the OH- concentration in blood? Calculate the pH of a 0.0128 M solution of the base pyridine (Kb=1.7x10^-9).
A system initially at 54 degrees Celcius experiences a change to 53 degrees Celcius. Did the system experience an endothermic or exothermic change and why? O Endothermic because heat left the system O Endothermic because heat was put into the system O Exothermic because heat left the system O Exothermic because heat was put into the system O More information is needed to answer this
why is this specific type of restriction enzyme useful for dna fongerprinting anaylisis?
Why do restriction enzymes need to be kept on ice? What order should the DNA, enzyme, water and buffer be added to the microcentrifuge tube for a restriction digest? If lambda DNA is linear, how many times would the enzyme have to cut the DNA to generate five DNA fragments? Would a shorter DNA fragment move faster or slower through the agarose gel than a longer fragment? Why?
College students performed the following set of restriction digests on their plasmid pBLA 230. The following below represents the enzyme, the number of bands produced, and the size of the DNA after going through gel electrophoresis. Draw the restriction map of the double digest.
This is a very simplistic approach to protein folding, which ignores solvent and volume effects, but it allows us to practice what we have learned about thermodynamics and kinetics. Enzymes are long chains of amino acids that have to fold in the proper way so as to exhibit enzyme activity. They can catalyze certain reactions. Let us pick an enzyme that is produced in the human body at 37 degrees celcius. We will call it enzyme X. Human enzymes exhibit...
Ethyl chloride (C2H5Cl) boils at 12 degrees celcius. When liquid C2H5Cl under pressure is sprayed on a room-temperature (25 degrees celcius) surface in air, the surface is cooled considerably. a) What does this observation tell us about the specific heat of C2H5Cl(g) as compared with C2H5Cl(l)? b) Assume that the heat lost by the surface is gained by ethyl chloride. What enthalpies must you consider if you were to calculate the final temperature of the surface?
2. hypothesize the best conditions (pH and temperature) under
which the enzyme chymotrypsin functions with an appropriate
reference. also, hypothesize what will occur in the presence of an
inhibitor and the type of inhibition.
EXPERIMENT 5: ENZYME ACTIVITY WITH a-CHYMOTRYPSIN Prelab Assignment 1. Prepare a flow chart, covering one half of the experimental work (either part A and C if your lab bench is on the window side of the lab or part B and D if your locker is...
Day 1, You have isolated DNA from 30 individuals and performed
restriction enzyme digestion. You have loaded the product and run
the gel electrophoresis following the instruction properly. You
expected to see DNA bands after the procedure is completed, like
figure A, but after the completion of the run your gel looks like
figure B. You did not see any DNA band. You were so upset, but your
lab partner fixed the problem and your gel looked like figure A....
