Read the following and answer any four questions from 2(i) to 2(v) given below: In prokaryotes, DNA is circular and present in the cytoplasm but in eukaryotes, DNA is linear and mainly confined to the nucleus. DNA or deoxyribonucleic acid is a long polymer of nucleotides. In 1953, the first correct double helical structure of DNA was worked out by Watson and Crick. Based on the X-ray diffraction data produced by Maurice Wilkins and Rosalind Franklin. It is composed of three components, i.e., A phosphate group, a deoxyribose sugar and a nitrogenous base. Different forms of DNA are B-DNA, Z-DNA, A-DNA, C-DNA and D-DNA.

Linkage between the nitrogen base and pentose sugar in DNA
Phosphodiester bond
The linkage present between the nitrogen base and pentose sugar in DNA is called a phosphodiester bond.
Definition:
A phosphodiester bond is a chemical bond that joins the phosphate group of one nucleotide to the hydroxyl group on the sugar of another nucleotide, forming the backbone of DNA and RNA molecules.
Formation:
During DNA replication and transcription, the phosphodiester bond is formed through a condensation reaction between the 3' hydroxyl group of the sugar of one nucleotide and the 5' phosphate group of the sugar of the next nucleotide. This reaction results in the formation of a covalent bond between the nucleotides and the release of a water molecule.
Importance:
The phosphodiester bonds play a crucial role in maintaining the stability and integrity of the DNA molecule. They link the individual nucleotides together in a specific sequence, forming the DNA strand. The sequence of nucleotides in the DNA molecule carries the genetic information that is essential for the functioning and development of living organisms.
Key points:
- The phosphodiester bond is formed between the phosphate group and the sugar (deoxyribose) of adjacent nucleotides.
- It forms the backbone of the DNA molecule.
- The bond is formed through a condensation reaction, releasing a water molecule.
- The sequence of nucleotides linked by phosphodiester bonds determines the genetic information encoded in the DNA molecule.
- The stability and integrity of DNA rely on the strength of the phosphodiester bonds.
Conclusion:
The linkage present between the nitrogen base and pentose sugar in DNA is a phosphodiester bond. This bond plays a vital role in maintaining the structure and function of DNA by linking the nucleotides together in a specific sequence.
