Answer this question…n Biology, a mutagen (Latin, literally origin of change) is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations cause cancer, mutagens are typically also carcinogens.

What is the Difference between a mutant and mutation?
A mutagen is a substance that CAUSES a mutation. Essentially, mutagens are the cause, mutations are the effect. Simple as that :)
Is mutagen an environmental factor that causes mutation?
It increases the odds of mutation.
What is physicial or chemical agents known as that can cause mutagen?
a change in the mRNA makes a mutation of the DNA
How can you use the mutation and mutagen in the same sentence?
by sucking your weener
What type of mutation occurs in reproductive cells and can be passed to offspring?
Sex cells
Why are revertants observed in Ames test?
To determine whether whatever chemical that was introduced to the bacteria is a mutagen. More revertants means better mutagen ie. the probability of a strain reverting back to wild-type is high since probability of a mutation in the DNA is high due to induced mutation by the mutagen. Less revertants means poor mutagen ie. the probability of a strain reverting back to wild-type is low since probability of a mutation in the DNA is attributed to just the probability of an error in replication.
What is the difference between a variation and a mutation?
mutation is an alteration in the nucleotide sequence of a gene whereas variation is any difference between individuals of a particular species.
Any agent which causes a change in DNA is a mutagen?
these are all mutagenic agents:-ultraviolet radiation from sunlight -free radicals that are formed as by-products of aerobic respiration -aflatoxins that are found in moldy grains
Which of the these would most likely cause a mutation?
A mutagen is a substance that has the potential to cause a mutation in the DNA.
What is the difference between mutation and variation?
variation is difference between genes and trait among individual* organism within population. mutation is change in genetic instruction I hope it helps
What is a gene mutation?
Gene mutation is the change in the DNA sequence that is permanent and leads to new genetic traits and even diseases. This type of mutation is triggered through hereditary process or through several factors in the environment.
What is a difference between a gene mutation and a chromosomes mutation?
a gene is passed on from generations and a chromosome is just found in certain cells
