Why does food dye that has been identified as a chemical mutagen poses as a greater danger for a developing fetus than for an adult?
Chemical Mutagens - Chemical mutagens can be divided into two classes those mutagens which can cause mutations to both replicating and non replicating DNA, are called as class I mutagens, those chemicals, which affect replicating nucleic acids are called as class II mutagens. So, a fetus is replicating DNA alot more than we are so im assuming that there is a higher risk for cell mutations in a fetus than a grown person :S not sure....i have to answer the same question as well. right now. BAH!
What are health effects of a mutagen chemical You have just learned of the chemical you work with is a mutagen?
A substance that causes a mutation <<< apexx It is any agent (such as, chemical) that is responsible for mutation, typically a genetic mutation. A mutagen is a substance which increases the frequency of mutation in a plant or animal population, which can lead to a variety of consequences. When DNA is copied, damage can be caused by physical and chemical agents know as Mutagens
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…
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.
Mutations are changes in the nucleotide sequences in a genome. Most often, these minor mistaks are corrected by in-built repair mechanisms and many mutations go unnoticed an are not harmful. Harmful mutations cause diseases in many cases. There are several factors that promote the formation of mutations. These factors are called mutagenic agents. Mutagenic agents are divided into: chemical and physical mutagens. UV radiation is an example of a physical mutagen and Nitrous acid is…
