Question
Bonds between these molecules are indicated by parentheses in dot-parentheses notation. Long-range bonds between these molecules form in the wrong order in a pseudoknot and can create a three-way junction in an aptamer. Pi stacking between these molecules stabilizes adjacent rungs of the stem of a hairpin. These heterocyclic molecules are linked by either two or three hydrogen bonds which (*) anneal around 60 degrees Celsius, but melt at 95 in a thermal cycler. A nitrogen atom in these molecules is bonded to the one-prime carbon of deoxyribose. The purine class of these molecules bonds to complementary pyrimidines to hold together the phosphodiester backbone. For 10 points, name these molecules that pair up in DNA. ■END■
ANSWER: DNA bases [or nitrogenous bases; or nucleobases; or nucleotides or nucleosides; accept base pairs; accept purines and pyrimidines until they are read; prompt on adenine or guanine or cytosine or thymine or A or C or G or T by asking “what class of molecules?”; prompt on nucleic acids or DNAs or RNAs or primers or oligonucleotides by asking “which part of the nucleic acid?”]
