- So my question is this. Considering that DNA polymerase cannot distinguish
- between dTTP and dUTP, how is it that dUTP is incorporated at such low rates?
- I have read the literature and it seems that there is no satifactory explana-
- tion.
- Viruses often encode their own set of enzymes for nucleotide synthesis, which
- in some cases is specialized to incorporate modified bases. But in most other
- cases, they encode thy. synthetase, etc. for the production of dTTP. This
- looks like a clue to me.
-
- I would greatly appreciate your thoughts and
- esp. any material you could point me toward so I could get a mathematical
- perspective on nucleotide synth. and dna replication.
-
- thanks.
