Operon :- Operon consists of a coordinated group of genes which are transcribed together and regulate a metabolic pathway as a unit. e. g. – Lac operon, trp operon, ara operon, his operon, val operon etc. e. g. – lac operator is present only in lac operon and it interacts specifically with lac repressor only.

Gene expression results in the formation of a polypeptide, it can be regulated at several levels. The genes in a cell are expressed to perform a particular function or a set of functions. Example 1. The development and differentiation of embryo into adult oranisms are a result of the coordinated regulation of expression of several
Translation :- It refers to the process of polymerisation of amino acids to form a polypeptide or protein. The order and sequence of amino acids are defined by the sequence of bases in the mRNA.
Genetic Code :- The genetic code was accomplished by the American biochemists – M. W. Nirenberg, R. W. Holley and Hargobind khorana in the early 1960. For example-the sequence of AUG is codon that specified the amino acid methionine. Table:- the codons for the various amino acids. Abbreviations used for the amino acids:- Ala- Alanine
