de novo and salvage pathways of nucleotides

Post by virlomi_stone » Thu Mar 23, 2006 7:40 am

In nucleotide biosynthesis are pyrimidines synthesized only by de novo pathways and purines synthesized only by salvage pathways or can they both be synthesized by either pathway?

I think the first part is the right answer but I keep confusing myself so I am not sure.

Thanks :)
