1.	In regular expressions, which of the following pair of pattern is wrongly matched with its significance?(a) [ ] – Or(b) { } – Not(c) ( ) – Repeats(d) Z – AnyThe question was asked by my school teacher while I was bunking the class.My question is based upon Motif and Domain Databases Using Regular Expressions topic in chapter Sequence Alignment of Bioinformatics
Answer» The correct answer is (d) Z – Any The explanation: Regular EXPRESSION SYMBOLS have their own significances in regular expressions systemmeans [GA] .g.e rFo ‘G or A’, {V,P} MEANS not P or V, x(4) means (xxxx). LIKEWISE, X denotes any character.

Unlike the commonly used methods for aligning a pair of sequences, the Bayesian method _______ using a particular scoring matrix or designated gap penalties.(a) does not depend on(b) depends on(c) is based on(d) involvesI had been asked this question in an online quiz.This interesting question is from Bayesian Statistics in portion Sequence Alignment of Bioinformatics
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
