Various codes are available which can correct different numbers or patterns of errors in the transmitted data. Such codes are used to achieve higher accuracy in data transmission, and in data storage devices such as disk drives and tape drives. object code Computers the arrangement of bits stored in computer memory or a data storage device which, when fed to the instruction processor of a computer's central processing unit, can be interpreted directly as instructions for execution. genetic code Biochemistry, genetics The set of correspondences between sequences of three bases (codons) in a RNA chain to the amino acid which those three bases represent in the process of protein synthesis. Thus, the sequence UUU codes for phenylalanine, and AUG codes for methionine. There are twenty-one naturally-occurring amino acids, and sixty-four possible arrangements of three bases in RNA; thus some of the amino acids are represented by more than one codon. Several codons do not represent amino acids, but cause termination of the synthesis of a growing amnio acid chain.
