Question

A multiple sequence alignment or a motif is often represented by a graphic representation called a ______

(a) logo

(b) motto

(c) algorithm

(d) algo

The question was posed to me by my college professor while I was bunking the class.

My enquiry is from Motif Discovery in Unaligned Sequences topic in section Sequence Alignment of Bioinformatics

Answer 1

The correct answer is:

(a) logo

In bioinformatics, a logo is a graphical representation used to display the results of a multiple sequence alignment or a motif. It typically shows the frequency of each amino acid (or nucleotide) at each position in the alignment, with taller letters representing more frequent residues at that position. This type of visualization helps in interpreting conserved regions and patterns within sequences.
