Concept introduction:
DNA stands for deoxyribonucleic acid, is a biological macromolecule. DNA contains double helical strands along with the complementary base pairs. The four complementary bases of DNA are adenine (A), thymine (T), guanine (G) and cytosine (C).
RNA stands for ribonucleic acid. The four complementary bases of RNA are adenine (A), uracil (U), guanine (G) and cytosine (C). Ribonucleic acid (RNA) is responsible for the synthesis of the molecules that carry out essential cellular functions.

- During the hydrolysis of proteins, some amino acids, such as tryptophan, do not survive the reaction conditions. Other amino acids, such as asparagine and glutamine, are modified. Referring to Table 1-7 (p. 39), which shows the structures of the 20 common amino acids, write the structures of the two amino acids that are formed when asparagine and glutamine decompose in hot, concentrated HCl.arrow_forward(a) What is the empirical formula of cellulose?
