Nucleotides and amino acids are distinct molecules with different chemical compositions and functions in biology. While the genetic code connects them indirectly through the process of protein synthesis, there is no direct complementarity or interaction between nucleotides and amino acids. Changes in genetic material are responsible for changes in amino acids in proteins. Changes in the genetic material (DNA) are responsible for changes in the amino acids that make up proteins. This process occurs through mutations, which are alterations in the DNA sequence.
