A generation 0 strain of E. coli had a transition temperature of 74.8 C . it was determined that by generation 43, the same strain of E coli DNA now had a transition temperature of 77.3 C. What can be said about the changes to the nucelobase composition over the 43 generations?
Homework Answers
Usually the organism living at higher temperature have higher GC CONTENT in their DNA when compared to the one living as mesophilic condition.high level of GC content stabilise the DNA more .
This infers that the DNA composition would have changed in such a manner that the net GC content is some how decreased due to mutation of any type.
The basic reason is that GC have 3 bonds while AT have 2 bonds.
i.e the GC content of DNA in 0 generation is more than that of 43 generation

10. Assume that a strain of E. coli is grown for many generations in SN, a heavy isotope of nitrogen (14N). Under this condition, assume that the DNA has a density of 1.723 gm/cm (with water being 1.00 gm/cm'). Assume that DNA containing only I'N has a density of 1.700. Bacteria from the SN culture were washed in buffer and transferred to 4N medium for one generation. DNA was extracted. a. What would the expected density of the extracted DNA?...

Strain R of E. coli has an RM system that modifies/cleaves the sequence GAATTC. Sometimes invading phage DNA is methylated by the strain R methylase before the endonuclease can cleave the viral DNA, and then replicates in the methylated form and forms viral particles. If you add some of these viral particles to uninfected bacteria of strain R, what will happen? Select one: a. The invading phage DNA is unmethylated and will be cleaved by the strain Rendonuclease b.

You
inoculate a strain of E. coli into a broth culture and allow it to
grow. The broth medium contains three sugars: glucose, lactose, and
maltose. The strain you are growing prefers lactose to maltose. You
measured the growth by doing a viable cell count and drew a growth
curve after calculating the number of CFU/ml over time. There was
an initial lag phase, followed by an exponential phase. There was a
second lag phase of approximately 30 minutes followed...
