When you hear the word sugar, the white table sugar used to sweeten tea and coffee may come to mind. However, the sugar in question in DNA is known as deoxyribose.
What Sugar Is Found In DNA?
What is the sugar found in DNA The correct option is B): Deoxyribose Sugar
Deoxyribose is the sugar present in DNA, whereas ribose is the sugar present in RNA. Pentoses include both ribose and deoxyribose.
One of the three elements that make up nucleotides—the building blocks of DNA—is deoxyribose. A phosphate group, a nitrogenous base (adenine (A), thymine (T), cytosine (C), or guanine (G)), and deoxyribose make up each nucleotide.
Deoxyribose, a 5-carbon sugar molecule, is present in DNA. DNA stands for deoxyribonucleic acid, and “deoxyribo” indicates which type of sugar makes up DNA’s nucleic acid.
What Is a Sugar-phosphate Backbone?
A DNA double helix has a twisted ladder-like appearance. The sugar-phosphate backbone is what’s referred to as the ‘ sides’ of the ladder, or the genetic strands. The sugar molecule of one nucleotide links to the phosphate group of the neighbouring nucleotide, forming an alternating backbone of phosphate and sugar groups.
Every sugar has a nitrogenous base attached to it. Pairs of nitrogenous bases form the rungs joining the two sugar-phosphate strands. These bases match in highly particular ways. G and C are always paired with A.
What sugar is found in DNA? One of the essential components of DNA is sugar. One of the two components of the sugar-phosphate backbone of all DNA strands is deoxyribose, which joins forces with a nitrogenous base to produce a nucleotide. These connect in large numbers in pairs to create DNA’s double helix structure.

What sugar is found in RNA?
Ribose sugar is found in RNA.
What type of sugar is found in DNA?
Deoxyribose sugar is found in DNA.
What is present in DNA?
DNA stores information in the form of a code of four chemical bases. These are adenine (A), guanine (G), cytosine (C), and thymine (T).
Why is DNA called deoxy?
The word “deoxy” means that the 2′ carbon atom has no oxygen charged to it.
