Thymine in spite of uracil.

hii!
it was a question that my teacher put it in a exam:
(it souds strange... anyway... )

related with the repairs' mechanisms of DNA, why thre´s Thymine in spite of uracil

THKSS!

in DNA nucleotides: Adenine,Guanine,Cytosine,Thymine and in RNA also A,G,C but instead of thymine is uracil(U). Seems ok question to me if I understood u correctly. If pairing is wrong it should be corrected by repair mechanism.

I don't think that U can be found in the DNA...

[chemistry_freako]

Yea - uracil's unqiue to RNA, complementary to adenine

Uracil can be the product of Cytosine deamination, hence they can be spontaneously formed, and produce mutation. But glycosylase are enzymes which are specially designed to repair this kind of mismatch.

thks for the answer!

Hey..btw, have you heard about strange unusual nitrogenous base name Hydroxymethylcytosine?? I think that N.base located in the bacteria chromosome..
