Explain how an E. coli cell that is deficient for proline synthesis (pro-) could become pro+ through the process of transduction.

Expert Solution

Transduction the process of genetic recombination in bacteria which involves viruses. Viruses which attack bacteria are called as bacteriophages. These virsues can infect a bacterial cell and insert their genome into it.

The genome of virus is integrated into the genome of of bacteria which directs bacteria to synthesise viral particles. When viral particles are completely assembled inside bacteria, then some of the bacterial genome is also packed with the viral genome inside viruses. These viruses then again enter new bacteria and can transfer the genome inherited from previous bacteria into the new bacteria. This is the way of that a proline negative bacteria can become proline positive.

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 = 2.00 μm/s , with an uncertainty in the velocity of 5.00 % . 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) Describe how you could determine quantitate (determine how many) E. coli cells have been transformed?

a) Describe how you could determine quantitate (determine how many) E. coli cells have been transformed? b) Briefly outline your experiment. You will need a control, or standard, to analyze your experimental results, make sure to indicate this in your answer – explain what the control/standard is and how you use it.
