The answer would be the interaction strengths of the relationships in the structure of the trophic community.
A major role of all trophic interactions in community stability are the interaction strengths. All species depend on one another. Some of these interactions are the population sizes and energy flow rates of each species as a whole or the biomass.
Aminoacyl-tRNA synthetases recognize their specific amino acid by charge, size and R group and recognize the tRNAs that carry it by the nucleotide sequence .
Aminoacyl-tRNA synthetases are enzymes that attaches the appropriate amino acids on to its tRNA . These are also responsible for performing the first step of protein synthesis.
