Question

What is deoxyribose sugar? Give the molecular structure of this sugar.

Answer 1

Hint: DNA has deoxyribose sugar, which forms the backbone of the double helix structure of DNA. It is a 5C containing ringed compound. one end of the sugar joins to the phosphate group while the other end joins to the nitrogenous bases.

Complete answer: Deoxyribose sugar is a 5 carbon ringed sugar which is the sugar that is found in the DNA. It is said to form the backbone of the DNA molecule.
It is known as deoxyribose sugar because of the absence of an Oxy or alcohol group in its 2nd carbon, which is found in the case of the ribose sugar. Ribose sugar is the one that is found in RNA. The molecular mass of deoxyribose sugar is 134.13g/mol and its chemical formula is $C_5{H}_{10}{O}_4$.

Additional information: The DNA (deoxyribonucleic acid) molecule, which is the main repository of genetic information in life, consists of a long chain of deoxyribose-containing compartments called nucleotides, linked through phosphate groups.
The double-stranded DNA molecules are typically much larger than RNA molecules.
The backbone of RNA and DNA is structurally the same, but RNA is single-stranded and made from ribose.

Note: Deoxyribose is the name of the sugar found in DNA and it is so named because it doesn't have a 2-C, OH group which is found in the Ribose sugar.
Ribose sugar is the pentose sugar that is found in the RNA.
