1.	The softwares for dot plot analysis perform several tasks. Which one of them is not performed by them?(a) Gap open penalty(b) Gap extend penalty(c) Expectation threshold(d) Change or mutate residuesI have been asked this question during an interview.My doubt is from Dot Matrix Sequence Comparison in division Sequence Alignment of Bioinformatics
Answer» Right answer is (d) Change or MUTATE residues Easiest explanation: The gap penalties mentioned above are for the determination of score of the ALIGNING sequences. The change in residue barely takes place as there are number of other softwares for that PURPOSE and also the main OBJECTIVE is to FIND the score of 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
