Bioinformatics Exhaustive Algorithms GK Quiz. Question and Answers related to Bioinformatics Exhaustive Algorithms. MCQ (Multiple Choice Questions with answers about Bioinformatics Exhaustive Algorithms
Which of the following scores are not considered while calculating the SP scores?
Options
A : All possible pair wise matches
B : All possible mismatches
C : All possible gap costs
D : Number of gap penalties
Which of the following is untrue about DCA?
Options
A : It stands for Divide-and-Conquer Alignment
B : It works by breaking each of the sequences into two smaller sections
C : The breaking points during the process are determined based on regional similarity of the sequences
D : If the sections are not short enough, further divisions are restricted as well
Which of the following cannot be related to multiple sequence alignment?
Options
A : Many conserved and functionally critical amino acid residues can be identified in a protein multiple alignment
B : Multiple sequence alignment is also an essential prerequisite to carrying out phylogenetic analysis of sequence families and prediction of protein secondary and tertiary structures
C : Multiple sequence alignment also has applications in designing degenerate polymerase chain reaction (PCR) primers based on multiple related sequences
D : This method does not contribute much to degenerate polymerase chain reaction (PCR) primers creation
As the amount of computational time and memory space required increases exponentially with the number of sequences, it makes the multidimensional search matrix method computationally prohibitive to use for a large data set.
Options
A : True
B : False
C :
D :
Related sequences are identified through the database similarity searching and as the process generates multiple matching sequence pairs, it is often necessary to convert the numerous pair wise alignments into a single alignment.
Options
A : True
B : False
C :
D :
The scoring function for multiple sequence alignment is based on the concept of sum of pairs (SP).
Options
A : True
B : False
C :
D :
There are two approaches viz. exhaustive and heuristic approaches used in multiple sequence alignment.
Options
A : True
B : False
C :
D :
There is a unique advantage of multiple sequence alignment because it reveals more biological information than many pair wise alignments can.
Options
A : True
B : False
C :
D :
Given a multiple alignment of three sequences, the sum of scores is calculated as the sum of the dissimilarity scores of every pair of sequences at each position.
Options
A : True
B : False
C :
D :
In a multidimensional search matrix, for aligning N sequences, an (N+2)-dimensional matrix is needed to be filled with alignment scores.
Options
A : True
B : False
C :
D :
