  • nucleobase
  • In DNA, the uracil nucleobase is replaced by thymine. (definitions.net)
  • Using state-of-the-art quantum dynamical methods that take the complex RNA environment into account, they found that the sterical influence of the RNA strand can obstruct the molecular motion necessary for the ultrafast relaxation of uracil and trap the nucleobase in the excited state for several picoseconds - long enough for harmful chemical reactions to occur.

  • gene
  • This study demonstrates that in nondividing Escherichia coli cells, a DNA template base replaced with uracil in a stop codon in the firefly luciferase gene results in conversion of inactive to active luciferase. (sciencemag.org)
  • mustard
  • If you are currently being treated or have recently been treated with uracil mustard, you should let your doctor know before receiving coccidioidin skin test. (drugs.com)
  • Depending on the dose and length of time you have been on uracil mustard, you may have a reduced response to the skin test. (drugs.com)
  • nucleobases
  • By considering different base sequences in their simulations, they also investigated whether specific combinations of neighboring nucleobases differ in their effects on the photostability of uracil. (uni-muenchen.de)
  • recognition
  • This interaction compresses the DNA backbone, bringing the UDG into closer proximity of the uracil, aiding its recognition. (kenyon.edu)
  • concentration
  • 1000 ng/ml are maintained throughout the 8-hour dosing interval, whereas uracil concentrations decline rapidly following the peak concentration. (drugbank.ca)
  • Name
  • Some of the dosage forms listed on this page may not apply to the brand name Uracil. (drugs.com)
  • backbone
  • The ultimate reaction catalyzed by UDG cleavage of the glycosidic bond between the uracil base and its corresponding deoxyribose sugar, releasing uracil from the DNA backbone. (kenyon.edu)
  • organic
  • Studies reported in 2008, based on ¹²C/¹³C isotopic ratios of organic compounds found in the Murchison meteorite, suggested that uracil, xanthine and related molecules were formed extraterrestrially. (definitions.net)
  • Results
  • These findings have convened with results that suggested that the degradation of 5-fluorouracil can be depressed by the addition of uracil. (drugbank.ca)
