What are three types of mutagens?
Mutagens may be of physical, chemical, or biologic origin. Examples of physical mutagens include Ultraviolet rays, radioactivity, and over high temperature. Examples of chemical mutagens include nicotine, pesticides, and methane. Examples of biologic mutagens include bacteria and viruses.
How can mutagens cause genetic mutations in spite of your body DNA repair enzymes?
Mutagens cause a change in DNA and by this way they can produce mutant DNA repair enzymes.
Fill in the blank Environmental causes of mutations are called?
mutagens
If you have just learned that a chemical you work with is a mutagenwhat effect does this chemical have?
A mutagen is a substance that can alter the DNA of an organism, potentially leading to genetic mutations. This can result in harmful changes in the genetic material, which may lead to negative effects like increased risk of cancer or other health issues. It is important to take precautions when working with mutagens to minimize exposure and potential risks.
Substances used to increase the rate of mutations?
Mutagens are substances that increase the rate of mutations by altering DNA, causing changes in the genetic material of an organism. Common mutagens include UV radiation, certain chemicals like ethidium bromide, and some viruses. These mutagens can lead to errors in DNA replication, resulting in genetic mutations.
What are three types of mutagens?
Mutagens may be of physical, chemical, or biologic origin. Examples of physical mutagens include Ultraviolet rays, radioactivity, and over high temperature. Examples of chemical mutagens include nicotine, pesticides, and methane. Examples of biologic mutagens include bacteria and viruses.
What are the main types of mutagens?
physical mutagens-e.g. uv radiation chemical mutagens-e.g. nitrous acid biological mutagens-e.g. viral infection
What is spontaneous and induced mutations?
Spontaneous mutations occur naturally due to errors in DNA replication, exposure to mutagens, or changes in cellular processes. Induced mutations are deliberately caused by exposure to external factors such as radiation, chemicals, or certain drugs to study the effects of specific genetic changes.

Which accurately describes the relationship between cancer risk and exposure to mutagens?
The relationship between cancer risk and exposure to mutagens is generally positive, as mutagens can cause changes in the DNA that lead to mutations, which are a key factor in cancer development. Increased exposure to mutagens, such as certain chemicals, radiation, or infectious agents, elevates the likelihood of acquiring mutations that may disrupt normal cell function and promote uncontrolled cell growth. Consequently, understanding and minimizing exposure to known mutagens is crucial in cancer prevention strategies.
What mutagens may produce genetic disorders?
nicotine in tobacco from cigarettes... can make cells mutate which is cancer
How does mutagens enter a human's body?
Mutagens can enter the human body through various routes such as inhalation, ingestion, and skin contact. Once inside the body, mutagens can disrupt DNA and lead to mutations that can potentially contribute to the development of cancer. It is important to minimize exposure to mutagens to reduce the risk of negative health effects.
Who discovered mutagens?
Barnes Devries

How many crystallization be induced?
crystallization may be induced through vigorous stirring, ice bath or through seeding.
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!
