Question
Chapter 9, Problem 35RE
Interpretation Introduction
Interpretation:
The most obvious characteristic of the base distribution of a single-stranded DNA molecule is to be explained.
Concept Introduction:
The X-ray diffraction pattern shows that the base-pairing is complementary, that is, purines always form bonds with pyrimidines. The adenine base pairs with the thymine base, while the guanine base pairs with cytosine base.
The mole percentages of both the bonded bases remain equal. The two strands are called complementary strands because of the existing complementarity of the base pairs.

- Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as ẞ-lactamase), an enzyme present in some penicillin-resistant bacteria. The mass of this enzyme in Staphylococcus aureus is 29.6 kDa.

The formation of the transition state is promoted.arrow_forwardThe graph displays the activities of wild-type and several mutated forms of subtilisin on a logarithmic scale. The mutations are identified as: • The first letter is the one-letter abbreviation for the amino acid being altered. • The number identifies the position of the residue in the primary structure. ⚫ The second letter is the one-letter abbreviation for the amino acid replacing the original one. • Uncat. refers to the estimated rate for the uncatalyzed reaction. Log₁(S-1) Wild type S221A H64A -5 D32A S221A H64A D32A -10 Uncat. How would the activity of a reaction catalyzed by a version of subtilisin with all three residues in the catalytic triad mutated compare to the activity of the uncatalyzed reaction? It would have more activity, because the reaction catalyzed by the triple mutant is approximately three-fold faster than the uncatalyzed reaction. It would have less activity, because the reaction catalyzed by the triple mutant is approximately 1000-fold slower than the…arrow_forward
