来自芝加哥大学，中科院上海药物研究所等处的研究人员发表了题为“Thymine DNA glycosylase specifically recognizes 5-carboxylcytosine-modified DNA”的文章，在之前研究基础上，进一步探讨了人类胸腺嘧啶DNA糖基化酶的结晶结构，以及分子机制，相关成果公布在Nature Chemical Biology杂志上。

The enzyme uracil DNA glycosylase (UNG) excises unwanted uracil bases in the genome using an extrahelical base recognition mechanism. Efficient removal of uracil is essential for prevention of C ...

For decades, scientists have known that DNA consists of four basic units -- adenine, guanine, thymine and cytosine. Those four bases have been taught in science textbooks and have formed the basis ...

Uracil vs. Thymine Uracil is often compared to thymine (T), which is the nucleobase that takes its place in DNA. Both uracil and thymine pair with adenine, but they differ in their chemical structure.

The mapping of 50,000 mysterious "knots" in the human genome may someday lead to the development of new cancer drugs, researchers say.

He found that the amount of adenine equalled that of thymine and the amount of guanine equalled that of cytosine but these were not equal to each other. The rough figures are: A=T=30% and G=C=20%.

There are four bases: Adenine and Guanine (purines); Cytosine and Thymine (Pyrimidines). Purines have two carbon-nitrogen rings while pyrimidines have a single carbon-nitrogen ring. Thus, there ...

Thymine (T) Uracil (U) 1950-1968: Development of knowledge about DNA Erwin Chargaff developed the understanding of the pairing of the adenosine, cytosine, guanine and thymine nucleotide bases in 1950.
