Optimal codons are specific sequences of codons preferred by a particular organism for protein synthesis, which enhance translational efficiency and accuracy by aligning with the available pool of tRNA molecules. These codons can vary between organisms, correlating with species-specific tRNA abundance, and are crucial for synthetic biology applications where gene expression is optimized by codon optimization strategies.

Protein synthesis is the cellular process through which genetic information is translated into functional proteins, essential for cellular structure and function. It involves two main stages: transcription, where DNA is converted into mRNA, and translation, where mRNA is decoded by ribosomes to assemble amino acids into polypeptide chains.

Protein Synthesis

Translational efficiency refers to the rate and accuracy at which a messenger RNA (mRNA) is translated into a protein by the ribosome. It is influenced by various factors including mRNA structure, codon usage, and the availability of tRNAs, ultimately impacting protein synthesis and cellular function.

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, typically proteins, which ultimately determine cellular function and phenotype. This process is tightly regulated at multiple levels, including transcription, RNA processing, translation, and post-translational modifications, to ensure proper cellular function and response to environmental cues.
