Nucleotides, which are the building blocks of nucleic acids, consist of a phosphate group, a nitrogenous base, and a

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.

the question isn't complete here so i can't right an answer '_'

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
