“However, as indicated above, the salvage pathway to thymidine nucleotide synthesis is especially important in the preparation for cell division.”

“A DNA substrate containing a thymidine kinase gene fused to a neomycin-resistance gene was stably integrated into cells.”

“Methionine synthase inhibition causes folate trapping and a reduction in the amount of folate available for thymidine synthesis as described above.”

“In DNA the bases pair to form a ladder-like structure, with adenine paired with thymine and guanine with cytosine.”

“Insertion of the thymine moiety into the angelicin skeleton caused a folding of about 51 of the cyclohexyl moiety.”

“These data confirm that cycloaddition occurs between the 8,9-double bond of HFQ and the 5,6-double bond of thymine.”

“Ultraviolet radiation joins adjacent thymines, creating thymine dimers, which, if not repaired, may cause mutations.”

“Special repair enzymes either cut the bond between the thymines or excise the bonded dimer and replace it with two single thymines.”

“Carmel's group looked for places in the ancient DNA where cytosines had morphed into thymines.”
