1.	In terminologies related to regular expressions which of the following is false about terms and operators?(a) Terms are strings or substrings(b) Operators combine terms and expressions(c) Operators do not have precedence(d) Operators have precedence like arithmetic operatorsThe question was asked during a job interview.This key question is from Motif and Domain Databases Using Regular Expressions in chapter Sequence Alignment of Bioinformatics
Answer» Correct CHOICE is (c) Operators do not have PRECEDENCE Easy EXPLANATION: For harmonious, efficient and error-free functioning of the MATCHING preocess, operators have precedence in order to SET the priority of the operations to be carried out during the alignment.

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
