[EX Q]: The tradition of birthday parties started in Europe a long time ago. It was feared that evil spirits were particularly attracted to people on their birthdays. To protect them from harm, friends and family members would come to stay with the birthday person and bring good thoughts and wishes. Giving gifts brought even more good cheer to keep away from the evil spirits. This is how birthday parties began. The following are some countries' birthday traditions: Canada---Putting butter on the nose. In Atlantic Canada, the birthday child's nose is put butter on for good luck. China---Noodles for lunch. The birthday child pays respect to his / her parents and receives a gift of money. Friends and relatives are invited to lunch and noodles are served to wish the birthday child a long life. England---Money cakes. Certain symbolic objects are mixed into the birthday cake as it is being prepared. If your piece of cake has a coin in it, you will be rich. Ireland---Birthday bump . The birthday child is lifted upside down and " bumped" on the floor for good luck. Italy---Pulling ears. The child's ears are pulled as many times as how old he / she is turning. Japan---New clothes. The birthday child wears new clothes to mark the occasion. New Zealand---Birthday claps. After the candles are hit, the happy birthday song is sung loudly and often out of tune and then the birthday person receives a clap for each year he / she has been alive and then one for good luck. The United States---Cake, candles and the birthday song. A cake is made, and candles are put on top based on how old the person is.

[EX Q]: We have determined sequences of PCR-amplified B1 elements from hamster and rat (Myomorpha), chipmunk (Sciuromorpha), and guinea pig (Caviomorpha). Between three and six B1 subfamilies were found in these species. In the phylogenetic analysis B1 sequences of hamster, mouse, and rat clustered separately from those of chipmunk and those of guinea pig. This is consistent with an independent evolution of B1 elements in separate rodent lineages. We exclude the possibility of convergent mutations to explain certain diagnostic characters within the modern B1 quasi-dimers and view these elements as mosaic structures assembling preexisting mutations. Furthermore, the presence of Alu-like structural motifs supports the hypothesis of the monophyletic origin of Alu and B1 repeats, i.e., from a common 7SL RNA-derived retroposing monomeric element.
[EX A]:
From which sequence does the Alu repeat originate from?
