What formula can be used to determine the pH in buffered chemical solutions?
The Henderson-Hasselbach formula, pH=pKa + log [A-/HA]. This formula can help solve for pH, pKa, A-, or HA when the remaining values within a buffered solution are known.
What are the three positively charged amino acids at a neutral pH?
Lysine, Arginine, and Histidine.
In biology, what does Chargaff's rule state, and what is its application?
Chargaff's rule states that there is a 1:1 ratio of purine in pyrimidine bases in double stranded DNA. It's application means that when the percentage of one purine is known (say adenine), the exact same percentage will apply to the other purine (guanine).
