Questions & Step-by-Step Solutions
What is the structure of a nucleotide?
Step 1: Understand that a nucleotide is a basic building block of DNA and RNA.
Step 2: Identify the three main components of a nucleotide: a sugar, a phosphate group, and a nitrogenous base.
Step 3: Recognize that the sugar can be either ribose (in RNA) or deoxyribose (in DNA).
Step 4: Know that the phosphate group is a molecule that contains phosphorus and oxygen.
Step 5: Learn that the nitrogenous base can be one of four types: adenine (A), thymine (T), cytosine (C), or guanine (G) in DNA; and adenine (A), uracil (U), cytosine (C), or guanine (G) in RNA.
