Mutagens in a sentence

Error in replication While most mutagens produce effects that ultimately result in errors in replication, some mutagens may directly affect the replication process.

Mutagens may stimulate unscheduled DNA synthesis that results in more stained nuclear material in cells following exposure to mutagens.

Types of mutagens Mutagens may be of physical, chemical or biological origin.

There are only two ways players can obtain Mutagens in ARK: Survival Evolved: crafting and farming Mutagen Bulbs.

These mutagens harvested from the powerful relict monsters are hardly worth the effort to acquire.

That prize validated Muller’s hypothesis and ultimately enshrined the LNT model as gospel, and it spread beyond ionizing radiation to other carcinogens and mutagens, as well as to many toxic chemicals in which, literally, the dose makes the poison.

But perhaps a copy will be changed and mutated for the worse by exposure to ambient radiation and other mutagens.

During this phase, synthesis is completed as quickly as possible due to the exposed base pairs being sensitive to harmful external factors such as mutagens Mitotic phase main The relatively brief M phase consists of nuclear division ( karyokinesis ).

However, some proposed that low level of some mutagens may stimulate the DNA repair processes and therefore may not necessarily be harmful.

In bacteria, extensive damage to DNA due to mutagens results in single-stranded DNA gaps during replication.

In disease TEs are mutagens and their movements are often the causes of genetic disease.

Initially, the ability of radiation and chemical mutagens to cause mutation was exploited to generate random mutations, but later techniques were developed to introduce specific mutations.

It is an easy, inexpensive and convenient initial screen for mutagens.

Many chemical mutagens require biological activation to become mutagenic.

Mutagenesis may also arise as a result of the presence of environmental mutagens that induce changes to the DNA.

Mutagens associated with cancers are often studied to learn about cancer and its prevention.

Mutagens identified in the Ames test need not necessarily be carcinogenic, and further tests are required for any potential carcinogen identified in the test.

Mutagens may also modify the DNA sequence; the changes in nucleic acid sequences by mutations include substitution of nucleotide base-pairs and insertions and deletions of one or more nucleotides in DNA sequences.

Mutagens that are not mutagenic by themselves but require biological activation are called promutagens.

Nitrosamines are an important group of mutagens found in tobacco, and may also be formed in smoked meats and fish via the interaction of amines in food with nitrites added as preservatives.
