S safeer

(a) Glucose doesn’t give 2,4-DNP test because the – CHO group in glucose is involved in hemiacetal formation and thus it is not free.

(b) The two strands in DNA are not identical but are complementary because the hydrogen bonds are formed between specific pairs of bases.

(c) Starch and cellulose both contain glucose unit as monomer, yet they are structurally different because Starch is a polymer of \alpha- glucose while cellulose is a polymer of \beta - glucose.
