Question

Which of the following is not a site on internet for alignment of sequence pairs?

(a) BLASTX

(b) BLASTN

(c) SIM

(d) BCM Search Launcher

The question was asked during an online interview.

I would like to ask this question from Dynamic Programming Algorithm for Sequence Alignment topic in chapter Sequence Alignment of Bioinformatics

Answer 1

The correct answer is:

(d) BCM Search Launcher

The BCM Search Launcher is not specifically a tool for sequence alignment. It is a tool for accessing a variety of bioinformatics databases and tools, but it is not directly used for aligning sequence pairs like BLASTX, BLASTN, or SIM.

• BLASTX and BLASTN are alignment tools used for comparing nucleotide sequences (BLASTX compares translated nucleotide sequences to protein sequences, while BLASTN compares nucleotide sequences to other nucleotide sequences).
• SIM is a sequence alignment tool that performs multiple sequence comparisons and aligns them based on similarity.

These tools are part of sequence alignment workflows, typically using dynamic programming algorithms for pairwise and multiple sequence alignments.
