INTERESTING FACTS
Which organism is the most common causative agent of urinary tract infections?
DNA replication. Okazaki fragments are the small segments of DNA that are formed on the lagging strand during DNA replication.
Escherichia coli. While all of these organisms can cause urinary tract infections, Escherichia coli, AKA E. coli, is the most common culprit.
Yersinia pestis. The bubonic plague epidemics were caused by Yersinia pestis. The bacteria was carried by fleas living on rats.
Neisseria gonorrhoeae. Neisseria gonorrhoeae is the causative agent of gonorrhea.
stain. Crystal violet, a stain, is fixed to the bacterial cell wall by the mordant, iodine. After decolorization and counterstaining with safranin, bacteria appear purple (gram positive) or pink (gram negative).
extreme cold. Extreme cold, while inhibiting the growth of most bacteria, does not usually kill them. And although heat and high and low pH will kill most known species of bacteria, certain species of Archaea can live in these extreme environments.
- F-plasmid. F-plasmid stands for fertility plasmid, although my biology class used a different mnemonic. :)
DNA replication. Okazaki fragments are the small segments of DNA that are formed on the lagging strand during DNA replication.
