Answer / visweswara rao
mutations are the changes in the gene sequences. it can be
occurred by physical mutations through radiations(uv, x-
rays),by chemical mutations by using nitrosoguanidine ems
etc.

Answer / suganthi
Mutations can be inherited. This means that if a parent has
a mutation in his or her DNA, then the mutation is passed
on to his or her children.
Mutations can be acquired. This happens when environmental
agents damage DNA, or when mistakes occur when a cell
copies its DNA prior to cell division.
Mutations in DNA sequences generally occur through one of
two processes:
DNA damage from environmental agents such as ultraviolet
light (sunshine), nuclear radiation or certain chemicals
Mistakes that occur when a cell copies its DNA in
preparation for cell division

Answer / ch.brahma reddy
According to modern concept the mutation is considerd to
sudden change in genotype of animal or a plant. Mutation
refers to any change in the base sequence of DNA.The most
change is a substitution,deletion rearangement,or a
deletion of one or more bases.

Answer / sowmya
Mutations are sudden changes that occur in the genome of an
organism.These sudden changes involves point mutations like
substitution, deletion or addition of base pairs which may
sometimes result in an altered phenotype.These mutations
may be caused by the physical agents like x-rays, uv rays
etc. or by chemical agents like ethyl methl sulphonate,
nitrous acid,hydoxyl amine,etbr and other carcinogens.
