2. In 1961, it was shown that the nucleic acid purine base adenine can be formed by heating aqueous ammonium cyanide solutions.
3. The preQ 1 riboswitch structure adopts a compact H-type pseudoknot, which makes it quite different from other purine based riboswitches.
4. The " pbuE " gene encodes a purine base terminator stem that had been blocking access to the gene expression platform.
5. Stable adducts may lead to DNA replication errors, while unstable adducts react with the DNA strand, removing a purine base ( either adenine or guanine ).
6. It's difficult to find purine base in a sentence. 用purine base造句挺难的
7. The structure of this molecule consists of a purine base ( adenine ) attached by the 92 nitrogen atom to the 12 carbon atom of a pentose sugar ( ribose ).
8. Each purine base is the Watson-Crick complement of a unique pyrimidine base ( and vice versa )  adenine and thymine form a complementary pair, as do guanine and cytosine.
9. In 2015, her article " Solution structures of purine base analogues 9-deazaguanine and 9-deazahypoxanthine " was published by the " Journal of Biomolecular Structure and Dynamics ".
10. A purine base always pairs with a pyrimidine base ( Guanosine ( G ) pairs with Cytosine ( C ) and Adenine ( A ) pairs with Thymine ( T ) or Uracil ( U ) ).
11. The Rev-ARM is a short peptide that represents the RNA binding domain of Rev . ( Right ) A rotated view showing the purine- purine base pairs ( yellow ) that widen the RNA major groove.
12. Apart from the Miller Urey experiment, the next most important step in research on prebiotic organic synthesis was the demonstration by Joan Or?that the nucleic acid purine base, adenine, was formed by heating aqueous ammonium cyanide solutions.
13. A Hoogsteen base pair applies the N7 position of the purine base ( as a hydrogen bond acceptor ) and C6 amino group ( as a donor ), which bind the Watson-Crick ( N3 & ndash; N4 ) face of the pyrimidine base.

This structure reveals an RNA A-form major groove widened by purine-purine base pairs at the purine-rich bulge to accommodate the a-helical Rev-ARM . Binding is achieved through a combination of base-specific contacts and electrostatic contacts with the phosphate backbone ( see figure ).
