It’s C because they took out the letter A from the new strand of DNA. btw deletion means to take away and substitution means to sub in a letter. hope that helped!
The four groups of pathogenic E.coli are enteropathogenic, enterotoxigenic, verocytotoxigenic and enteroinvasive groups. These groups can best be isolated and recoved through luria broth.
<h3>What is Escherichia coli?</h3>
The pathogenic E. coli or Escherichia coli serotypes are grouped on the basis of their mechanism of causing symptoms in humans. The six groups of pathogenic E.coli are enteropathogenic, enterotoxigenic, verocytotoxigenic, enteroinvasive, enteroaggregative and diffusely adherent E. coli.
Luria broth (LB) is one of the most commonly used growth medium for E. coli. It promotes fast growth of the organism and also provides good plasmid yields, making it an excellent choice for most laboratory applications, especially the small-scale plasmid preps.
