Question

Sugar found in DNA is
A. Dextrose
B. Laevulose
C. Glucose
D. Deoxyribose.

Answer 1

In the DNA deoxyribose sugar and in the RNA ribose sugar present in it. On the second carbon of deoxyribose Sugar is present and on the ribose hydroxyl group is present. The phosphate backbone of DNA molecules present at the five carbon Sugar molecules and nucleic acid made with the help of polymer.

Complete answer:
DNA molecules contain the sugar, nitrogen bases and phosphate group in each molecule; these nitrogenous bases are adenine (A), guanine( G), thymine ( T), and cytosine (C). These nucleotides bases order according to the genetic code. And the nucleic acids present in the DNA structure are a kind of polymer. And purines and pyrimidine are the two nitrogenous bases present in it and ribose and deoxyribose two sugars are present inside the structure.
With the help of naturally occurring compounds nucleic acid is a compound that is capable of being broken down to phosphoric acid, purines pyrimidines and sugars. By the process of protein synthesis the nucleic acids are the main information carrying molecules of the cells. Deoxyribose acid and ribonucleic acids are the two main classes of the nucleic acids.

Therefore the correct option is (D).

Note: Deoxyribose molecules bind with the two phosphate groups pyrimidine and purine. An organism that needs to develop life and reproduction with the help of a molecule that contains the instructions of an organics. These instructions are passed from parents to daughter’s cells. And nearly every cell in the person's body has the same kind of DNA. And made up of DNA molecules known as nucleotides.
