Protein coding is a fundamental process in molecular biology where the genetic information stored in DNA is used to synthesize proteins. This process occurs in two main stages: transcription and translation. In transcription, a segment of DNA is copied into a molecule of messenger RNA (mRNA) by the enzyme RNA polymerase. This mRNA then serves as a template for protein synthesis during translation. Translation occurs in the cytoplasm and is catalyzed by ribosomes, which read the mRNA sequence in groups of three nucleotides called codons. Each codon corresponds to a specific amino acid, the building blocks of proteins. The sequence of amino acids determined by the mRNA sequence folds into a specific three-dimensional structure, which gives the protein its unique function. Protein coding is essential for various biological processes, including growth, development, and metabolism. Mutations in the DNA sequence can lead to changes in the amino acid sequence of proteins, potentially resulting in diseases such as cystic fibrosis or sickle cell anemia. Understanding protein coding is crucial for fields such as genetics, biotechnology, and medicine.
