Here are the essential concepts you must grasp in order to answer the question correctly.
Codons
Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids or stop signals during protein synthesis. There are 64 possible codons, but only 20 standard amino acids, leading to redundancy in the genetic code. This means that multiple codons can code for the same amino acid, which is crucial for understanding which amino acids have the most codons.

Amino Acids
Amino acids are organic compounds that serve as the building blocks of proteins. There are 20 standard amino acids, each defined by its unique side chain or R group. Some amino acids, like leucine and serine, are encoded by multiple codons, making them more versatile in terms of genetic coding and important for understanding the distribution of codons among amino acids.

Genetic Code Redundancy
Genetic code redundancy refers to the phenomenon where multiple codons can specify the same amino acid. This redundancy provides a buffer against mutations, as changes in the DNA sequence may not always lead to changes in the protein produced. Understanding this concept is essential for identifying which amino acids have the most codons, as it highlights the relationship between codon usage and amino acid frequency.
