purine bases造句
例句与造句
- In DNA, the purine bases are adenine and guanine, while the pyrimidines are thymine and cytosine.
- Most notable among the changes in DNA are the 1, 2-intrastrand cross-links with purine bases.
- Deamination of purine bases can result in accumulation of such nucleotides as ITP, dITP, XTP, and dXTP.
- This enzyme then metabolically processes the PAHs to quinone metabolites that bind to DNA in reactive adducts that remove purine bases.
- To date, the human AAG ( hAAG ) is the only glycosylase identified that excises alkylation-damaged purine bases.
- It's difficult to find purine bases in a sentence. 用purine bases造句挺难的
- Both RNA and DNA contain two major purine bases, adenine ( A ) and guanine ( G ), and two major pyrimidines.
- The anthraquinone component allows for specific binding of DNA at the 3 side of purine bases through intercalation, a site that is different from calicheamicin.
- The pyrimidines, thymine, cytosine and uracil, form the complementary bases to the purine bases in DNA and RNA, and are also components of UTP.
- A DNA triplex is formed when pyrimidine or purine bases occupy the major groove of the DNA double Helix forming Hoogsteen pairs with purines of the Watson-Crick basepairs.
- The bonds for chloride would be replaced by the aqua bonds which would bind to two purine bases, with Guanine favored over Adenine in the major groves of DNA adducts.
- In cells, AAG is the enzyme responsible for recognition and initiation of the repair, via catalysing the hydrolysis of the N-glycosidic bond to release the alkylation-damaged purine bases.
- Because of the asymmetry in pyrimidine and purine use in coding sequences, the strand with the greater coding content will tend to have the greater number of purine bases ( Szybalski's rule ).
- The dienone alkylates the purine bases ( adenine and guanine ) of DNA, and then the alkylated purine parts are spontaneously removed from DNA : subsequently the cleavage of DNA occurs ( DNA damage ).
- It is isolated from " Streptomyces sahachiroi " which is reisolated from " analog azinomycin A . Azinomycin B can bind within the major groove of DNA and forms covalent interstrand crosslinks ( ISCs ) with the purine bases.
- In addition, dsDNA ( double stranded DNA ) in the active site has a wider major groove and shallower minor groove that permits the formation of hydrogen bonds with the third nitrogen of purine bases and the second oxygen of pyrimidine bases.
