1.	In a type of probability, analysis is to calculate the odds score for one event OR a second event, or of a series of events. In this case, the odds scores are _______(a) multiplied(b) subtracted(c) added and multiplied(d) addedI had been asked this question in an internship interview.The doubt is from Bayesian Statistics in chapter Sequence Alignment of Bioinformatics
Answer» Right option is (d) added To explain: An EXAMPLE is the calculation of the ODDS score for a given sequence alignment using a series of alternative PAM SCORING matrices. The alignment scores are calculated in log odds units and then CONVERTED into odds scores.

Who suggested that the global alignment scores between unrelated protein sequences followed the extreme value distribution, similar to local alignment scores? And when?(a) Abagyan and Batalov, in 1981(b) Chvátal and Lipman, in 1984(c) Abagyan and Batalov, in 1997(d) Chvátal and Sankoff, in 1995This question was posed to me during an interview.I'd like to ask this question from Assessing the Significance of Sequence Alignments topic in portion Sequence Alignment of Bioinformatics
The higher is the score in the alignment _________(a) the more significant is the alignment(b) or the less it resembles alignments in related proteins(c) the less significant is the alignment(d) the less it aligns with the related protein sequenceThe question was posed to me during an online interview.The question is from Dynamic Programming Algorithm for Sequence Alignment topic in division Sequence Alignment of Bioinformatics
