Question:

Two acids are in equilibrium with each other. One has a pKa of 10, while the other has a pKa of 20. Which acid will have the highest concentration at equilibrium?

Inactive

Answer:

Equilibrium lies in the direction of the higher pKa, which is also the weaker acid. In this case, the acid with a pKa of 20 will have the higher concentration.

Question:

Describe the structure of DNA (as specific as possible) and explain why it is significant.

Answer:

DNA is found in the nucleus as a double stranded helix. Each strand is made of nucleotides (A, T, C, and G) attached to a backbone (deoxyribose and phosphate). The double strand means that each side can be copied without getting rid of the original material!
