The pentose sugars present in nucleotides have five-carbon structures. Other components of a nucleotide are a phosphate group and a nitrogenous base. The nitrogenous base in a nucleotide can be a purine or pyrimidine. The purine bases are covalently joined to the 1' carbon atom of the pentose sugar at their N-9. The bond between the nitrogenous base and a pentose sugar is called the N-beta glycosyl bond.
Similarly, N-1 of a pyrimidine base is covalently linked to the 1' carbon of the pentose sugar. The phosphate group of a nucleotide is bonded to the 5' carbon of the pentose sugar.
Gene which is responsible for the production of spruceanol in the Peruvian Rosewood plant can be inserted in the host species in order to produce spruceanol in large quantity so that we can used it as a drug that can cure antimalarial disease. There are certain genes that are responsible for the production of spruceanol in the Peruvian Rosewood plant so if we want to produce this spruceanol in other plants we have to transfer this gene to the host plant.
