Compared to [18 F]FHBG, N-Me-[18 F]FHBT showed a higher background radioactivity in most tissues . Webbcompared with 17.5 resin-bed-volumes for thymine. From a comparison of the specific activities of the added thymine and the re-covered thymidine it was calculated that the isotope exchange was at least 96 % complete. The chemical recovery of thymidine was 70 to 75%, giving an over-all recovery of radioactivity as thymidine-2-C14 of 40 to 45 % ...

Thymidine Metabolism in Bacteria (and “How, or How Not, to
Thymine (symbol T or Thy) is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The others are adenine, guanine, and cytosine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase. In RNA, thymine is replaced by the nucleobase uracil. Thymine was first … Visa mer As its alternate name (5-methyluracil) suggests, thymine may be derived by methylation of uracil at the 5th carbon. In RNA, thymine is replaced with uracil in most cases. In DNA, thymine (T) binds to adenine (A) … Visa mer In March 2015, NASA scientists reported that, for the first time, complex DNA and RNA organic compounds of life, including uracil, cytosine and thymine, have been formed in the laboratory under outer space conditions, using starting chemicals, such as Visa mer • Deoxyribose • Deoxythymidine • Nucleobase • Pyrimidine • Thymineless death • Uracil Visa mer During growth of bacteriophage T4, an imbalance of thymine availability, either a deficiency or an excess of thymine, causes increased mutation. The mutations caused by thymine deficiency appear to occur only at AT base pair sites in DNA and are often AT to GC Visa mer Laboratory synthesis Thymine was first prepared by hydrolysis of the corresponding nucleoside obtained from natural … Visa mer • Thymine MS Spectrum • Infoplease Encyclopedia • Science Aid: DNA Structure and Replication Visa mer WebbLorsque les cellules synthétisent de l'ADN, elles incorporent ce précurseur et l'ADN formé est alors radioactif.
