Draw the monosaccharide present in DNA. Draw the sugar in its ?-furanose form.
Concepts and reason
This problem is based on the concept of structure of sugar present in DNA.
Deoxyribose nucleic acid (DNA) is a compound that carries on the genetic information from one generation to another generation in order to pass on the genetic traits.
Fundamentals
DNA consists of a sugar molecule, a nitrogenous base and phosphate groups which give it a rigid structure in order to sustain in biological environment.
Answer:
Monosaccharide present in the DNA is deoxyribose and its structure is given below:
Explanation:
Deoxyribose is formed by ribose sugar which contains five carbon atoms and does not have any hydroxyl group at carbon-2. Thus, it is named as deoxy.
Furanose structure of monosaccharide present in DNA is given below:
Explanation:
Deoxyribose is formed by ribose sugar which contains five carbon atoms and does not have any hydroxyl group at carbon-2. Thus, it is named as deoxy. Furanose form of deoxyribose nucleic acid contains a five-membered ring in which four atoms are carbon atoms and one atom is oxygen.
