In genetics, a mutagen is a physical or chemical agent that changes the genetic material DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore likely to be carcinogens, although not always so. All mutagens have characteristic mutational signatures with some chemicals becoming mutagenic through cellular processes. Not all mutations are caused by mutagens: so-called "spontaneous mutations" occur due to spontaneous hydrolysis, errors in DNA replication and recombination; the first mutagens to be identified were carcinogens, substances that were shown to be linked to cancer. Tumors were described more than 2,000 years before the discovery of chromosomes and DNA. C. the Greek physician Hippocrates named tumors resembling a crab karkinos. In 1567, Swiss physician Paracelsus suggested that an unidentified substance in mined ore caused a wasting disease in miners, in England, in 1761, John Hill made the first direct link of cancer to chemical substances by noting that excessive use of snuff may cause nasal cancer.
In 1775, Sir Percivall Pott wrote a paper on the high incidence of scrotal cancer in chimney sweeps, suggested chimney soot as the cause of scrotal cancer. In 1915, Yamagawa and Ichikawa showed that repeated application of coal tar to rabbit's ears produced malignant cancer. Subsequently, in the 1930s the carcinogen component in coal tar was identified as a polyaromatic hydrocarbon, benzopyrene. Polyaromatic hydrocarbons are present in soot, suggested to be a causative agent of cancer over 150 years earlier; the association of exposure to radiation and cancer had been observed as early as 1902, six years after the discovery of X-ray by Wilhelm Röntgen and radioactivity by Henri Becquerel. Georgii Nadson and German Filippov were the first who created fungi mutants under ionizing radiation in 1925; the mutagenic property of mutagens was first demonstrated in 1927, when Hermann Muller discovered that x-rays can cause genetic mutations in fruit flies, producing phenotypic mutants as well as observable changes to the chromosomes, visible due to presence of enlarged'polytene' chromosomes in fruit fly salivary glands.
His collaborator Edgar Altenburg demonstrated the mutational effect of UV radiation in 1928. Muller went on to use x-rays to create Drosophila mutants, he found that X-rays not only mutate genes in fruit flies, but have effects on the genetic makeup of humans. Similar work by Lewis Stadler showed the mutational effect of X-rays on barley in 1928, ultraviolet radiation on maize in 1936; the effect of sunlight had been noted in the nineteenth century where rural outdoor workers and sailors were found to be more prone to skin cancer. Chemical mutagens were not demonstrated to cause mutation until the 1940s, when Charlotte Auerbach and J. M. Robson found that mustard gas can cause mutations in fruit flies. A large number of chemical mutagens have since been identified after the development of the Ames test in the 1970s by Bruce Ames that screens for mutagens and allows for preliminary identification of carcinogens. Early studies by Ames showed around 90% of known carcinogens can be identified in Ames test as mutagenic, ~80% of the mutagens identified through Ames test may be carcinogens.
Mutagens are not carcinogens, vice versa. Sodium azide for example may be mutagenic. Mutagens are therefore genotoxic, they can affect the transcription and replication of the DNA, which in severe cases can lead to cell death. The mutagen produces mutations in the DNA, deleterious mutation can result in aberrant, impaired or loss of function for a particular gene, accumulation of mutations may lead to cancer. Mutagens may therefore be carcinogens. However, some mutagens exert their mutagenic effect through their metabolites, therefore whether such mutagens become carcinogenic may be dependent on the metabolic processes of an organism, a compound shown to be mutagenic in one organism may not be carcinogenic in another. Different mutagens act on the DNA differently. Powerful mutagens may result in chromosomal instability, causing chromosomal breakages and rearrangement of the chromosomes such as translocation and inversion; such mutagens are called clastogens. Mutagens may modify the DNA sequence.
Although some of these mutations are lethal or cause serious disease, many have minor effects as they do not result in residue changes that have significant effect on the structure and function of the proteins. Many mutations are silent mutations, causing no visible effects at all, either because they occur in non-coding or non-functional sequences, or they do not change the amino-acid sequence due to the redundancy of codons; some mutagens can change the number of chromosomes in the cell. They are known as aneuploidogens. In Ames test, where the varying concentrations of the chemical are used in the test, the dose response curve obtained is nearly always linear, suggesting that there may be no threshold for mutagenesis. Similar results are obtained in studies with radiations, indicating that there may be no safe threshold for mutagens. However, the no-threshold model is disputed with some arguing for a dose rate dependen

"Yung Rapunxel" is a song recorded by American singer/rapper Azealia Banks for her debut studio album titled Broke with Expensive Taste. Interscope Records released the song as the album's first single to mainstream radio on April 16, 2013; the track contains an interpolation of the song "No More Drama" by R&B singer Mary J. Blige. On March 11, 2013, the song was made available for online streaming via SoundCloud; the song was performed by Banks during the Glastonbury Festival in June 2013. "Yung Rapunxel" was set to be released on March 26, 2013. However, on March 28, 2013, it was announced that the single would drop on April 16, 2013; the first single from Broke With Expensive Taste was planned to be "Miss Amor/Miss Camaraderie". On January 28, 2013, Banks acknowledged that the first single was going to be "Yung Rapunxel"; the original release date, the February 12, was delayed to March, again, delayed to April 16, 2013. For unknown reasons, it is now unavailable on iTunes UK. On March 9, the artwork for the single was released via Banks' Twitter account.
Michael Depland from MTV Buzzworthy described "Yung Rapunxel" as a 1990s Hi-NRG-influenced hip house song, built on a busy witch hop beat. Meanwhile, The Guardian's Alex Macpherson detailed the track as an industrial number. Spin's Marc Hogan wrote that the song "comes across as a reinvention for her, though it doesn't have quite that track's memorable catchphrases... Banks has left seapunk behind to go where she belonged all along: another galaxy". MTV's Michael Depland believed that on the track, "A bona fide hip-house banger, Azealia rhymes slickly over a busy witch-hop beat", that Banks is "back spitting fire over a manic'90s HI-NRG-influenced track, cut in between muffled hollers". Shooting for the music video began on February 22, 2013, was continued into March; the official music video was released on April 16, 2013. The video was created by visual artist Jam Sutton; the video features a black-and-white setting, including police running through mist, owls with yellow and red eyes flying in suspended motion, Banks riding a mechanical bull, a rotating Yin & Yang symbol, a disembodied hand with an eye embedded in the palm floating in mid air and Banks with mouths for eyes.
