definition
noun
Among the mutagens that have been used to induce mutations, chemical mutagens administered in various ways have become especially popular.
an agent, such as radiation or a chemical substance, that causes genetic mutation.
example
For genetics and breeding, it is fundamentally important to know the germline mutation rate induced by a 'mutagen' .
One possible explanation for these exceptional findings might be contamination of the ethanol with a 'mutagen' .
But we can provoke a quicker second hit by treating the animals with a chemical 'mutagen' or a carcinogen.
He was preeminent in the fields of 'mutagenesis' and radiation biology.
Significantly, their findings were supported by both in vivo and in vitro experiments using reference 'mutagens' .
Poisons, 'mutagens' , and carcinogens might be created in harmful concentrations.
Exposure to ionizing radiation or environmental 'mutagens' and carcinogens may lead to genomic instability.
The so-called Ames test is based on the fact that most carcinogens are 'mutagens' (substances that damage DNA).
Firstly, risks to the descendants of trial participants because of the inadvertent modification of germ cells are not identical to those for chemical 'mutagens' .
These 'mutagens' cause point mutations, because they change the genetic code at one point, so changing a protein's amino acid sequence.
Lead is clearly not a powerful mutagen, nor is it consistently 'mutagenic' among various test systems.
The purpose of this study was to determine if cooked meat containing only moderate concentrations of the known food 'mutagens' would be detectably mutagenic.
Males were fed prior to 'mutagenesis' because starved males did not mate after mutagen treatment.
She devoted her career to an understanding of DNA 'mutagenesis' and the nature of DNA repair mechanisms.
Substances which allow the Salmonella to grow are considered 'mutagenic' .
Many carcinogens and mutagens have to be metabolized before their 'mutagenic' activity can be detected.
A host of carcinogens spew forth, along with poisons, 'mutagens' , and mind-altering drugs.
Unlike most chemical 'mutagens' , which tend to cause point mutations, rays tend to produce larger aberrations such as chromosome deficiencies or rearrangements.
Chemical mutagens and ionizing radiation have long been used as plant 'mutagens' in forward genetic studies.
The integrity and stability of the genetic material is continuously being threatened by endogenous and exogenous factors such as chemical 'mutagens' and radiation.
This cell line detects a wide variety of 'mutagenic' lesions, including point mutations, deletions and various types of chromosomal aberrations.
We carried out several rounds of 'mutagenesis' for each chromosome arm.
According to experimental data, some pesticides and organic solvents are considered potential chemical 'mutagens' .
We show here that these strains can be used to determine very easily the mutagenic specificity of various 'mutagens' .
Chemicals that cause changes in DNA sequence, or mutations, are called 'mutagens' .
Cell-culture procedures, chemical 'mutagens' , and radiation all have been applied in what people now refer to as traditional, or conventional, plant breeding for the better part of a century.
This suggests a 'mutagenic' source different from germ cell replication.
Among the mutagens that have been used to induce mutations, chemical 'mutagens' administered in various ways have become especially popular.
Detection of low frequency mutations following exposure to 'mutagens' or during the early stages of cancer development is instrumental for risk assessment and molecular diagnosis.
We and others have shown that studies of 'mutagenesis' in cultured mammalian cells can help predict carcinogenesis.
