Decoding Life: How Codon Charts Translate Nucleotides into Amino Acids
The genetic code—a universal language written in DNA and RNA nucleotides—governs protein synthesis in all living organisms. A codon chart serves as the essential decoder for this language, mapping triplets of nucleotides (codons) to specific amino acids. This systematic correspondence enables cells … Decoding Life: How Codon Charts Translate Nucleotides into Amino AcidsRead more
