Extra Information :-

~~~~~~~~~~~~~~~~

• Different classes of Chemical Mutagens have different modes and rates of action.

• Some Chemical Mutagens imitate bases (called base analogues) and replace them during the replication of D.N.A. molecules.

• When a base analogue is phosphorylated, it acquires the tendency to get incorporated into D.N.A. molecules.

• "Hydroxylamine" (NH₂OH) is commonly used as a chemical mutagen in chemical laboratories and industries.

• "Nitrous acid" (HNO₂) is a potent chemical mutagen.

• "Nitrous acid" (HNO₂) causes de-amination of Cytosine thus, creating Uracil.

• Alkylating agents comprise of an extremely large group of very potent chemical mutagens.

• Alkylating agents are used extensively in the synthesis of of several economic products such as Plastic.

• Alkylating agents have been widely used in warfare in the form of poisonous gases known as "Mustard Gases".

• "Mustard Gases" cause extremely painful deaths by adversely acting on the Skin, Mucosal membranes and Lungs.

• Alkylating agents cause mutations through Transitions, Transversions, Deletions, and Frameshifts.
