Arealsearcher was performing a test to check the effect of induced point mutation. but the experimental nous could not survive. what might be the reason

The reason  for this is most likely a lethal mutation. This is a mutation where the  effects can result in the death of an organism carrying the mutation.  It's also known as a lethal factor or lethal gene.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
