Genetics: Biosynthesis pathway of a new DNA nucleobase elucidated
DNA is composed of nucleobases represented by the letters A, T, G and C. But in a bacteriophage, another base, represented by the letter Z, exists. Scientists from the Institut Pasteur and the CNRS, in collaboration with the CEA, have now elucidated the biosynthesis pathway of this base. This work has been published in the April 30th, 2021 issue of Science.
