In the canonical Watson-Crick base pairing, adenine (A) forms a base pair with thymine (T) and guanine (G) forms one with cytosine (C) in DNA. In RNA, thymine is replaced by uracil (U). Alternate hydrogen bonding patterns, such as the wobble base pair and Hoogsteen base pair, also occur--particularly in RNA--giving rise to complex and functional tertiary structures. Importantly, pairing is the mechanism by which codons on messenger RNA molecules are recognized by anticodons on transfer RNA during protein translation. Some DNA- or RNA-binding enzymes can recognize specific base pairing patterns that identify particular regulatory regions of genes. Hydrogen bonding is the chemical mechanism that underlies the base-pairing rules described above. Appropriate geometrical correspondence of hydrogen bond donors and acceptors allows only the ``right'' pairs to form stably. DNA with high GC-content is more stable than DNA with low GC-content, but contrary to popular belief, the hydrogen bonds do not stabilize the DNA significantly and stabilization is mainly due to stacking interactions.
 Question: can rna exist in a variety of secondary structures Context: The Bank of Scotland was suspected of Jacobite sympathies. Its first rival, The Royal Bank of Scotland was formed by royal charter in 1727. This led to a period of great competition between the two banks as they set to drive each other out of business. Although the ``Bank Wars'' ended in around 1751, competition soon arose from other sources, as other Scottish banks were founded throughout the country. In response, the Bank of Scotland itself began to open branches throughout Scotland. The first branch in London opened in 1865.

Production was to begin at the start of 2009, but was delayed while the script was completely re-written by Matthew Michael Carnahan to set the film in the present, leaving behind much of the book's premise to make it more of an action film. In a 2012 interview, Brooks stated the film now had nothing in common with the novel other than the title. Filming commenced mid-2011, and the film was released in June 2013.
