What is the sugar found in each nucleotide of RNA called?

In RNA (ribonucleic acid), the sugar component of each nucleotide is called ribose. Ribose is a five-carbon sugar that is an essential part of RNA's structure. Each nucleotide in RNA consists of a ribose sugar, a phosphate group, and a nitrogenous base, which can be adenine, uracil, cytosine, or guanine.

Desoxyribose, on the other hand, is the sugar present in DNA (deoxyribonucleic acid) and lacks one oxygen atom compared to ribose, which is why it is specifically associated with DNA. Glucose is a simple sugar and does not feature in the structure of either RNA or DNA nucleotides. Sucrose is a disaccharide composed of glucose and fructose, and it also does not play a role in the structure of RNA or DNA. Therefore, ribose is the correct term that describes the sugar found in each nucleotide of RNA.
