Mutations in two regulatory genes of white grapes turn off production of anthocyanins which are responsible for the color of purple grapes.

Mutations are changes in the DNA sequence of a cell's genome and are caused by radiation, viruses, transposons and mutagenic chemicals, as well as errors that occur during meiosis or DNA replication.

Mutations in transpeptidases that lead to reduced interactions with an antibiotic are a significant source of emerging antibiotic resistance.

Mutations that affect insulin-like signaling in worms, flies, and the growth hormone / IGF1 axis in mice are associated with extended lifespan.

Mutations are permanent, transmissible changes to the genetic material ( usually DNA or RNA ) of a cell.

Mutations are considered the driving force of evolution, where less favorable ( or deleterious ) mutations are removed from the gene pool by natural selection, while more favorable ( or beneficial ) ones tend to accumulate.

Mutations leading to the loss of function of a gene are much more common than mutations that produce a new, fully functional gene.

Mutations in the tafazzin gene ( TAZ, also called G4. 5 ) are closely associated with

Mutations periodically occur within the Y chromosome and these mutations are passed on to males in subsequent generations.

Mutations of the genes VHL, RET, NF1 ( Gene 17 Neurofibromatosis type 1 ), SDHB and SDHD are all known to cause familial pheochromocytoma / extra-adrenal paraganglioma.

Mutations are characterized as either β < sup > o </ sup > or β thalassemia major if they prevent any formation of β chains, the most severe form of β thalassemia.

Mutations are the ultimate source of genetic variation because they alter the order of bases in the nucleotides of DNA.

Mutations are likely to be rare and most mutations are neutral or deleterious, but in some instances the new alleles can be favored by natural selection.

Mutations in the Ras family of proto-oncogenes ( comprising H-Ras, N-Ras and K-Ras ) are very common, being found in 20 % to 30 % of all human tumours.

Mutations in this gene are rare.

Mutations affecting repressor are said to be recessive to wild type ( and that wild type is dominant ), and this is explained by the fact that repressor is a small protein which can diffuse in the cell.

Mutations usually sound at pitches in the harmonic series of the fundamental and, except where they are derived from unit ranks, are always tuned pure.

Mutations within the desmosome are the main cause of Arrhythmogenic right ventricular cardiomyopathy ( ARVC ).

Mutations of the WT1 gene on chromosome 11 p 13 are observed in approximately 20 % of Wilms ' tumors .< ref > At least half of the Wilms ' tumors with mutations in WT1 also carry mutations in CTNNB1, the gene encoding the proto-oncogene beta-catenin.

Mutations in BRCA1 and BRCA2, important risk factors for ovarian cancer and breast cancer in women, have also been implicated in prostate cancer.

Mutations in the surface proteins allow the virus to elude some host immunity, and the numbers and locations of these mutations that confer the greatest amount of immune escape has been an important topic of study for over a decade.

Mutations in any of these genes prevent the proper production or assembly of the type IV collagen network, which is an important structural component of basement membranes in the kidney, inner ear, and eye.

Mutations of SDHB play an important role in familial adrenal pheochromocytoma and extra-adrenal paraganglioma ( of abdomen and thorax ), although there is considerable overlap in the types of tumors associated with SDHB and SDHD gene mutations.

Mutations and natural selection result in a species acquiring new traits and eventually evolving into one or more new species.

game as well as adding sophisticated new rule systems specific to the setting ( e. g. Mutations and ' Weird Science ').

Mutations in the gene for the prion protein can cause a misfolding of the dominantly alpha helical regions into beta pleated sheets.

Mutations of the corresponding gene in mice ( FOXP2 is fairly well conserved ; modern humans share the same allele as Neanderthals ) cause reductions in size and vocalization rate.

Mutations in several genes have been linked to several types of epilepsy.

One deck represents random Alpha Mutations, which can be drawn to gain temporary powers, and the other contains various Omega Tech, powerful technological devices that could possibly backfire on those that use them.

Mutations in the genes for the hemoglobin protein in a species result in hemoglobin variants.

Mutations of the thyroid-stimulating hormone receptor that cause a constitutive activation of the thyroid gland cells have been discovered recently.

Mutations in the gene HR can lead to complete hair loss, though this is not typical in humans.

Mutations can have an impact on the phenotype of an organism, especially if they occur within the protein coding sequence of a gene.

Mutations can involve large sections of DNA becoming duplicated, usually through genetic recombination.

Mutations can involve large sections of DNA becoming duplicated, usually through genetic recombination.

Mutations in such microRNAs ( known as oncomirs ) can lead to activation of oncogenes.

Mutations that deactivate p53 in cancer usually occur in the DBD.

Mutations in viral genes weakened their infectious ability, sometimes creating viruses that were able to infect and grow within only certain varieties of E coli.

Mutations du surréalisme de l ' exil américain à l ' écart absolu ( 1941 – 1965 ), Les presses du réel, Dijon, 2007.

Mutations of the Chardonnay grape include the rare pink-berried " Chardonnay Rose "; also " Chardonnay Blanc Musqué ", which produces an intensely aromatic wine.

Mutations in genes can cause also affect skin colour through oculocutaneous albinism ( OCA ) – a lack of pigment in the eyes, skin and sometimes hair that occurs occasionally in a very small fraction of the population.

Mutations of this very polymorphic gene, such as Arg151Sys ( rs1805007 ), Arg160Trp ( rs1805008 ), Asp294Sys ( rs1805009 ), Val60Leu ( rs1805005 ) and Val92Met ( rs2228479 ) have been shown to cause red hair and pale skin that does not tan in a small percentage of the human population.
