The genetic code defines how codons in DNA/RNA are translated into amino acids during protein synthesis.
The genetic code is the set of rules used by living cells to translate genetic information stored in DNA or RNA sequences (as nucleotide triplets called codons) into proteins. During translation, the ribosome reads mRNA three nucleotides at a time, while transfer RNA (tRNA) molecules deliver specific amino acids in the order specified by those codons. In most cases, each codon corresponds to a single amino acid, and the code can be represented in a 64-entry table (with some exceptions such as variant codes found in mitochondria). The purpose of the genetic code is to ensure that the sequence of nucleotides in a gene is converted into a specific protein sequence, thereby enabling protein biosynthesis. Because the genetic code is highly similar across organisms and is largely “canonical” (standard), it provides a universal framework for how genetic information becomes functional biological molecules. Stop codons also play a key role by signaling termination of translation when no matching tRNA is available, preventing the ribosome from producing an incorrect or overly long protein.
The genetic code defines how codons in DNA/RNA are translated into amino acids during protein synthesis.
Translation is carried out by the ribosome using tRNA to match codons to amino acids, reading mRNA in triplets.
Most codons specify a single amino acid, and the standard code is commonly summarized with 64 entries, though variant codes exist.
Stop codons signal termination of translation, ensuring proteins are produced with correct length and sequence.
The set of rules that translates nucleotide triplets (codons) in DNA or RNA into the amino-acid sequence of proteins.
A sequence of three nucleotides in mRNA that specifies a particular amino acid (or a stop signal).
The ribosome-driven process that converts mRNA codon sequences into a polypeptide by using tRNA-delivered amino acids.
Transfer RNA molecules that carry specific amino acids and read mRNA codons during translation.
A codon (such as UAA, UAG, or UGA) that signals the ribosome to terminate protein synthesis.
