Which of the following is untrue about PRRN?


aPRRN is a web-based program that uses a double nested iterative strategy for multiple alignment

✖


b It performs multiple alignments through two sets of iterations: inner iteration and outer iteration

✖


cIn the outer iteration, an initial random alignment is generated that is used to derive a UPGMA tree

✖


dIn the inner iteration, the sequences are randomly divided into multiple groups

✓


View Answer In the inner iteration, the sequences are randomly divided into multiple groups

Which of the following is untrue about iterative approach?


aThe iterative approach is based on the idea that an optimal solution can be found by repeatedly modifying existing suboptimal solutions

✖


bBecause the order of the sequences used for alignment is different in each iteration

✖


c This method is also heuristic in nature and does not have guarantees for finding the optimal alignment

✖


dThis method is not based on heuristic methods

✓


View Answer This method is not based on heuristic methods

Which of the following is untrue regarding T-Coffee?


a It stands for Tree-based Consistency Objective Function for alignment Evaluation

✖


bIt performs progressive sequence alignments as in Clustal.

✖


c The global pair wise alignment is not performed using the Clustal program.

✓


dThe local pair wise alignment is generated by the Lalign program, from which the top ten scored alignments are selected

✖


View Answer The global pair wise alignment is not performed using the Clustal program.

Which of the following is not a drawback of the progressive alignment method?


aThe progressive alignment method is not suitable for comparing sequences of different lengths because it is a global alignment–based method

✖


b In this method the use of affine gap penalties, long gaps are not allowed, and, in some cases, this may limit the accuracy of the method

✖


cIn this method the use of affine gap penalties, long gaps is allowed, and, in some cases, this may limit the accuracy of the method

✓


dThe final alignment result is also influenced by the order of sequence addition

✖


View Answer In this method the use of affine gap penalties, long gaps is allowed, and, in some cases, this may limit the accuracy of the method

Which of the following is untrue regarding the Progressive Alignment Method?


aProgressive alignment depends on the stepwise assembly of multiple alignments and is heuristic in nature

✖


bIt speeds up the alignment of multiple sequences through a multistep process

✖


cIt first conducts pair wise alignments for each possible pair of sequences using the Needleman–Wunsch global alignment method and records these similarity scores from the pair wise compariso

✖


d Its drawback is it slows down the alignment of multiple sequences through a single step process

✓


View Answer Its drawback is it slows down the alignment of multiple sequences through a single step process
