Biomolecules Figure-Based Questions for NEET

Observe the given figure and answer the following questions.

(a) Identify the labelled parts A, B and C in the given figure.

A. In the given figure of double helical structure of DNA,

A-represents hydrogen bonds,

B-represents glycosidic bond and

C-represents sugar-phosphate backbone

(b) Briefly describe the given figure.

A. The given figure indicates the secondary structure of DNA. One of the secondary structures exhibited by DNA is the famous Watson-Crick model. This model says that DNA exists as a double helix. The two DNA chains are antiparallel. In one chain the direction is 5′ → 3′ while in the opposite is it is 3′ → 5′. The two chains are held together by hydrogen bonds between their bases. Adenine (A), a purine of one chain lies exactly opposite thymine (T), a pyrimidine of the other chain. Similarly, cytosine (C, a pyrimidine) lies opposite guanine (G, a purine). This allows a sort of lock and key arrangement between large-sized purine and small-sized pyrimidine. It is strengthened by the appearance of hydrogen bonds between the two. Three hydrogen bonds occur between cytosine and guanine (C ≡ G) at positions 1 – 1′, 2′ – 6′, and 6′ – 2′. There are two such hydrogen bonds between adenine and thymine (A = T) which are formed at positions 1′ – 3′ and 6′ – 4′. Hydrogen bonds occur between hydrogen of one base and oxygen or nitrogen of the other base.
