What key ingredient is required in every step in the process of translating from DNA to mRNA to tRNA into a polypeptide chain?

1. Enzymes
2. Codons
3. Amino acids
4. Ribose

ENZYMES!! any chemical change in our bodies is monitored by ENZYMES!! Its like these DNA ----> Enzyme------> mRNA------> enzyme------> tRNA i mean codons AA and Robose are important, but enzymes are always going to supervise the changes
