Answer:
Two
Explanation:
Since the Earth rotates through two tidal “bulges” every lunar day, we experience two high and two low tides every 24 hours and 50 minutes.
The DNA is zipped open by the enzyme DNA helicase, to form two singles strands of DNA for that specific area of the DNA.
Then RNA nucleotides are joined to the sense strand to form a complementary strand of RNA, the RNA is small enough to leave the nucleus by the nuclear pores and go to the ribosomes. This process is called transcription
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.
