An example is the formation of pyrimidine dimers in DNA, which begins at wavelengths below 365 nm (3.4 eV), which is well below ionization energy. Source: Internet
Aspartate carbamoyltransferase also ensures that just the right amount of pyrimidine nucleotides is available, as activator and inhibitor molecules attach to aspartate carbamoyltransferase to speed it up and to slow it down. Source: Internet
Aspartate carbamoyltransferase performs a step in building the pyrimidine nucleotides ( cytosine and thymidine ). Source: Internet
Synthesis In a scholarly article published in October 2009, NASA scientists reported having reproduced uracil from pyrimidine by exposing it to ultraviolet light under space-like conditions. Source: Internet
Most UV-induced pyrimidine dimers in DNA are removed by the process known as nucleotide excision repair that employs about 30 different proteins. Source: Internet
