Difference Between Mutagen and Teratogen

Difference Between Mutagen and Teratogen

Mutagens induce DNA damage that either kills cells or when mis-repaired, produces abnormal sequences that will be passed on to daughter cells. These actions, in turn, induce birth defects. ... A teratogen is an agent capable of causing malformations in embryos (birth defects).

What is the difference between carcinogens mutagens and teratogens?

Mutagens cause changes (mutations) in the genetic material of cells. Teratogens cause irreversible, deleterious structural malformations in fetuses. ... Carcinogens cause cancerous tumors with a characteristically crablike appearance.

What is the difference between a mutagen and a carcinogen?

mutagens affect DNA in a non specific way with regards to cancer. Carcinogens affect DNA in a way as to make cancer more likely.

What is an example of a teratogen?

Teratogens are substances that may produce physical or functional defects in the human embryo or fetus after the pregnant woman is exposed to the substance. Alcohol and cocaine are examples of such substances. ... The word teratogen originates from the Greek word for monster, teratos.

What is the meaning of teratogens?

Teratogen: Any agent that can disturb the development of an embryo or fetus. Teratogens may cause a birth defect in the child. Or a teratogen may halt the pregnancy outright. The classes of teratogens include radiation, maternal infections, chemicals, and drugs.

How do teratogens cause birth defects?

Polychlorinated biphenyls, also known as PCBs, are shown to cause fetal growth restriction and skin discolouration. X-rays can cause problems with fetal development, such as spina bifida, cleft palate, blindness, abnormalities of the arms and legs, or microcephaly, which is a condition where the brain is too small.

Can carcinogens cause birth defects?

- A new study suggests that exposure of a fetus to common carcinogens during the late stages of pregnancy may be even more harmful than exposure after birth, causing long-lasting genetic damage that could lead to cancer in childhood, young adulthood or even middle age.

Is a virus a mutagen?

Abstract. Injections into Drosophila melanogaster males of 9 DNA- and RNA-containing viruses non-infectious for this insect, proved that all of them are highly mutagenic, inducing numerous gene mutations or microdeletions but no gross chromosome rearrangements.

What are 3 types of mutagens?

Three different types of common mutagens are observed in nature- physical and chemical mutagens agents and biological agents.

What is a carcinogen example?

A carcinogen is an agent with the capacity to cause cancer in humans. Carcinogens may be natural, such as aflatoxin, which is produced by a fungus and sometimes found on stored grains, or manmade, such as asbestos or tobacco smoke. Carcinogens work by interacting with a cell's DNA and inducing genetic mutations.

Is caffeine a teratogen?

In humans, caffeine does not present any teratogenic risk. The increased risk of the most common congenital malformations entailed by moderate consumption of caffeine is very slight.

What is the most common teratogen?

The tranquilizer thalidomide is one of the most famous and notorious teratogens. This hypnotic agent was used widely in Europe in 1959, after which an estimated 7000 infants were born with the thalidomide syndrome or meromelia.

What are 2 common teratogens?

Teratogenic agents include infectious agents (rubella, cytomegalovirus, varicella, herpes simplex, toxoplasma, syphilis, etc.); physical agents (ionizing agents, hyperthermia); maternal health factors (diabetes, maternal PKU); environmental chemicals (organic mercury compounds, polychlorinated biphenyl or PCB, ...
