                                             Mutation  A sightly change in the sequence of  DNA  which may be transmitted to further generation caused by  the addition  , deletion or alternation of single base of DNA is  known as Mutation . Classification - Mutation can be classified into two ways Acquired Mutation - The mutation which is not occur in our body but it is acquired from other source are known as Acquired Mutation . For example Ultraviolet rays that sometime cause Cancer in body by mutation in DNA . The only advantage in this type of mutation is that it is not transformed to further generation and  limited in some of the cells of  the body . Hereditary Mutation -  The mutation which is transformed from parents to offspring are known as Hereditary Mutation . When the egg cell and sperm cell unite they form fertilized egg . This fertilized egg receives DNA from both the parent and  if this DNA have mutation then obviously child that grow have mutation in ever

                                            Enzyme Enzymes play a very important role in our life. They are specialized proteins with catalytic activities and a great degree of specificity.  All the living beings need enzymes for their biochemical reaction in which reaction starts with substrate and end in the product . Therefore Enzymes are also called Biocatalyst. Characteristics Of Enzyme - Enzymes are highly specific in nature. All enzymes are proteinaceous in nature. Enzymes always catalyze the reaction. They act actively at optimum temperature. They are colloidal in nature. Inhibitor always inhibits the enzymatic reaction. Enzymes are manufactured in the living cells but they are non-living. E nzyme  Classificatio n - According to the international union of biochemist (IUB), enzymes can be classified into six classes- Oxidoreductase - It involves oxidation, reduction, and electron transfer. For example, alcohol dehydrogenase. Transferase -It invol
