mutatioon is a genetic change in the dna

mutations can be occur by physicalagents such as x-rays,
radio active elements.
chemical agents-acrylic dyes,benz pyrenes.
biological agents-afflotoxin,tobbaco

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 / ajay rana

1. Mutation in genes can occur by chance in nature(Random
Mutation)
2. Mutation can be induced in genes by chemicals in lab

Answer / leela

by chenging the genetic codans in dna

Answer / kathir

mutation occur in two way in nature its by uv and x rays.
some chemicals like ethidium bromide form the mutations.
thaiamine dimer mutations.

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 / leela

mutations occur by exposing to U.V.RAYS , X rays or with
radio active chemicals.

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.

Answer / santoshi

mutations are sudden heritble changes that occur in the
dna ...mutations can caused by physical agents like
x.rays..and also by chemical agents
