Answer:

Ribose sugar

Explanation:

Nucleic acids are polynucleotides, which are composed of a long chain molecules of nucleotides. Each nucleotide is made up of:

1. Nitrogen-containing base, which can be Adenine, Guanine, Cytosine and Thymine or Uracil (depending on whether it is DNA or RNA)

2. A phosphate group, which is a phosphorus atom attached by a covalent bond to four oxygen atoms (PO4). The arrangement makes it able to store high energy.

3. A five-carbon sugar known as ribose, the ribose sugar can either be without oxygen (deoxyribose) as in DNA or with oxygen as in RNA.
