The Genetic Code and Translation. In molecular biology and genetics, translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus.The entire process is called gene expression.. Meaning of Genetic Code: The genetic code may be defined as the exact sequence of DNA nucleotides read as three letter words or codons, that determines the sequence of amino acids in protein synthesis. The genetic code is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins by living cells. >For example, UGA can be code for Selenocysteine (now viewed as 21 amino acid) and UAG can code for Pyrrolysine (viewed as 22nd amino acid).
>Genetic code is Universal except few mitochondrial codes and, small variants such as translation of the codon UGA as Tryptophan in the species Mycoplasma and translation of CUG as Serine rather than Leucine in the genus Candida.
