10. The amount of DNA in one E. coli cell is found to be 5 fg (femtogram, 10-15 g). Given that the molecular weight of one base pair of DNA is 600 Dalton and 1 Dalton equals 1.66 x 10-24 g, how many base pairs of DNA are there in one E. coli cell?
A. 1.8 x 106
B. 2 x 106
C. 5 x 106
D. 7.2 x 106
E. None of the above

The bacterium E. Coli is a Gram-negative rod that is 1mM x 2mM. Each E. Coli cell contains a chromosome of 4 x 106bp of double-stranded DNA. Since 1 kilobase pair (kbp) of double-stranded DNA is 0.340mM in length, what is the length of the E. Coli chromosome? (1 kbp = 1000 base pairs, and 1mM = 10-6meters). A single colony-forming unit (CFU) of E. coli contains 109 cells. If you were to join all the E. coli chromosomes contained in that colony together...

A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 1.80 fg (where a femtogram, fg, is 10−15g) and is swimming at a velocity of v = 6.00 μm/s , with an uncertainty in the velocity of 4.00 % . E. coli bacterial cells are around 1 μm ( 10−6 m) in length. The student is supposed to observe the bacterium and make a drawing. However, the student, having just...

A student is examining a bacterium under the microscope. The E, coli bacterial cell has a mass of m = 1.90 fg (where a femtogram, fg. is 10^-15 g) and is swimming at a velocity of upsilon = 9.00 mu m/s, with an uncertainty in the velocity of 5.00%. E. coli bacterial cells are around 1 mu m (10^-6 m) in length. The student is supposed to observe the bacterium and make a drawing. However, the student, having just learned...

Error rates in DNA replication, proofreading and mismatch repair systems in E. coli are about 10-10 per base pair per round of replication. Based on this, how many mutations per base pair would you expect to see in a population of 1010 E. coli cells (e.g. of a TSB culture of E. coli)
