Question: In 1955, the diaries of Napoleon's valet, Louis Marchand, were published. His description of Napoleon in the months before his death led Sten Forshufvud in a 1961 paper in Nature to put forward other causes for his death, including deliberate arsenic poisoning. Arsenic was used as a poison during the era because it was undetectable when administered over a long period. Forshufvud, in a 1978 book with Ben Weider, noted that Napoleon's body was found to be remarkably well preserved when moved in 1840. Arsenic is a strong preservative, and therefore this supported the poisoning hypothesis. Forshufvud and Weider observed that Napoleon had attempted to quench abnormal thirst by drinking large amounts of orgeat syrup that contained cyanide compounds in the almonds used for flavouring.

Answer: When were the diaries of Napoleon's valet published?

Question: In cpDNA, there are several A G deamination gradients. DNA becomes susceptible to deamination events when it is single stranded. When replication forks form, the strand not being copied is single stranded, and thus at risk for A G deamination. Therefore, gradients in deamination indicate that replication forks were most likely present and the direction that they initially opened (the highest gradient is most likely nearest the start site because it was single stranded for the longest amount of time). This mechanism is still the leading theory today; however, a second theory suggests that most cpDNA is actually linear and replicates through homologous recombination. It further contends that only a minority of the genetic material is kept in circular chromosomes while the rest is in branched, linear, or other complex structures.

Answer: What kind of gradients does cpDNA have?
