Concept explainers
(a)
Interpretation: We need to comprehend the corresponding sequence of base in new and parent strand DNA.
Concept Introduction: DNA parent strand forms the daughter strand in which the bases are bonded in complementary way to parent strand.
(b)
Interpretation: The mRNA sequence should be determined.
Concept Introduction: The molecule in living cells which carry codes from DNA in the nucleus to the ribosomes, which are the sites of protein synthesis in the cytoplasm are said to be messenger RNA or mRNA.
(c)
Interpretation: 3-letter abbreviations for the amino acids that would go into the peptide from the mRNA of part (b) should be determined.
Concept Introduction: A codon represents the sequence of three DNA or RNA

- Q.1 Three given polypeptides (P, Q and R), of same size and same pl (7.2), have a single aspartic acid in each of them. In polypeptide P, the aspartic acid residue is on the surface. In polypeptide Q, it is surrounded by negatively charged residues, whereas in polypeptide R it is deeply buried in a hydrophobic core. pKa of the side chain carboxylate of free (in solution) aspartic acid is 3.65. The polypeptides are in a buller of pH 7.4. The clange in pKa of the aspartic acid side chain carboxylate in the polypeptides P, Q and R is likely to, Ans remain the same in P, modest increase in Q and greater increase in R X2. remain the same in all the three polypeptides X3. increase in P, decrease in Q and remain the same in R X 4. remain the same in P, increase Q and decrease in R.arrow_forward18.50 Draw the condensed structural formula for a and b and the line-angle formula for c and d. a. hexanamide b. 3-methylbutanamide c.
