Question
Chapter 25, Problem 7PP
Interpretation Introduction
Interpretation:
The structural formula showing hydrogen bonds between lactam form of guanine and thymine are to be written and further indicate the consequences it might have onto the complementary strand during the next replication cycle.
Concept Introduction:
Normally, in DNA, guanine occurs in the lactam form and pairs with cytosine by forming three hydrogen bonds. When guanine tautomerizes to lactam form, it pairs with thymine instead. This mispairing then passes on to the daughter DNA (deoxyribonucleic acid) formed during replication and hence, brings about permanent changes called mutations.

An orange laser has a wavelength of 610 nm. What is the energy of this light?
The molar absorptivity of a protein in water at 280 nm can be estimated within ~5-10% from its content of the amino acids tyrosine and tryptophan and from the number of disulfide linkages (R-S-S-R) between cysteine residues:
Ε280 nm (M-1 cm-1) ≈ 5500 nTrp + 1490 nTyr + 125 nS-S
where nTrp is the number of tryptophans, nTyr is the number of tyrosines, and nS-S is the number of disulfide linkages. The protein human serum transferrin has 678 amino acids including 8 tryptophans, 26 tyrosines, and 19 disulfide linkages. The molecular mass of the most dominant for is 79550.
Predict the molar absorptivity of transferrin.
Predict the absorbance of a solution that’s 1.000 g/L transferrin in a 1.000-cm-pathlength cuvet.
