Which of the following has the ability to develop ester linkage with the OH group of Pentose sugar?
Correct answer: C. H3PO4
- A. Purine
- B. Pyrimidine
- C. H3PO4
- D. HNO3
Explanation
DNA and RNA consist of many nucleotides joined together by special ester linkages called phosphodiester bonds. Two nucleotides are linked by the phosphodiester bond which is formed by the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another. Two hydroxyls (OH) groups on the phosphate molecule bind to the 3' and 5' carbons on two independent pentose sugars to link the two nucleotides.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
