Question

what are the three components of a nucleotide? sugar, oxygen, nitrogen base sugar, phosphate, protein sugar, hydrogen, nitrogen base sugar, phosphate, nitrogen base

Explanation:

A nucleotide is composed of three main parts. The sugar component is either ribose (in RNA) or deoxyribose (in DNA). The phosphate group is crucial for forming the backbone of nucleic acids. The nitrogen - base (such as adenine, thymine, cytosine, guanine in DNA and adenine, uracil, cytosine, guanine in RNA) is responsible for the genetic code.

• In the first option, oxygen is not a separate component of a nucleotide. The oxygen is part of the sugar and other groups.
• In the second option, protein is not a component of a nucleotide. Proteins are made up of amino acids.
• In the third option, hydrogen is part of the sugar and other groups and is not a separate named component of a nucleotide.

Answer:

sugar, phosphate, nitrogen base
