Q: In molecular biology, two nucleotides on opposite complementary DNA or RNA strands that are connected via hydrogen bonds are called a base pair (often abbreviated bp). 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.
Can we conclude that can rna exist in a variety of secondary structures?

Q: In November 2008, the show's post-election day telecast garnered the biggest audience in the show's history at 6.2 million in total viewers, becoming the week's most-watched program in daytime television. It was surpassed on July 29, 2010, during which former President Barack Obama first appeared as a guest on The View, which garnered a total of 6.6 million viewers. In 2013, the show was reported to be averaging 3.1 million daily viewers, which outpaced rival talk show The Talk.
Can we conclude that is the talk the same as the view?
OPTIONS:
- no
- yes
A: no

Q: Kershaw Knives was started in Portland, Oregon in 1974 when knife salesman Pete Kershaw left Gerber Legendary Blades to form his own cutlery company based on his own designs. Early manufacturing was primarily done in Japan. In 1977, Kershaw became a wholly owned subsidiary of the KAI Group. In 1997 the U.S. production facility was opened in Wilsonville, Oregon. Due to an expanding market, the facilities were moved to a larger production site in 2003. Currently, Kai USA manufacturing facilities are located in Tualatin, Oregon with some goods coming from their Japanese and Chinese factories.
Can we conclude that are all kershaw knives made in the usa?
OPTIONS:
- no
- yes
A: no

OPTIONS:
- no
- yes
A:
no
