Question

What are nucleotides?

Answer 1

Nucleotides are the four nitrogen-containing nucleobases that make up the structures and both DNA and the proteins and enzymes that allow the functioning of the organs in the human body. These nucleobases are A, T, G, and C, or Adenosine, Thymine, Guanine, and Cytosine.

If one of these bases were to change, then this would lead to a complete change in the specific protein that it codes for, and if there is too much or too little of a specific enzyme or protein, then this can lead to mutation of the human DNA, and these mutations can be either harmful, useful, or not have any effect at all.
