PROTEINS

The word proteins is the most heard term in the study of dna and genes. so what is protein???
It is one of the fundamental material in the structure of most living things.Proteins are the organic compounds made of amino acids arranged in a linear chain and folded into a globular form.Like other biological macromolecules proteins are essential parts of organisms and participate in every process within the cells.
Proteins are assembled from amino acids using information encoded in genes.Each protein has its own unique amino acid sequence that is specified by the nucleotide sequence of the gene encoding this protein.The process of synthesizing a protein from an mRNA template is known as translation.So Proteins are the chief actors within the cell, said to be carrying out the duties specified by the information encoded in genes.They are one of the building blocks in the cell.And also proteins serve as enzymic catalysts also.And proteins are important for regulating physiological processes, energy production within the body's structure.
