Abstract
: Protein structure prediction play a key role in every living organisms All living organisms are made up of cells and
each cell in its turn consists of certain protein consequences which exercise an important role in catalyzing the chemical
reactions. So, a study of a protein structure becomes a search lamp in the diagnosis of a disease .when the percent identity
between two protein sequences falls below 33%,it necessities to carry out the analysis of protein secondary structure. Of the
several methodologies developed to analyze the protein secondary structure, two methods proved to be soundDSSP(Dictionary
of Secondary Structure of Proteins) and GOR(Garnier,Osguthrope and Robson),Even though the prediction
accuracy of GORV is 73.5% due to hazards in its implementation ,GORIV is generally used in spite of its accuracy being only
to 64.4%
