Question

The overall height of a logo position reflects how conserved the position is, and the _____ of each letter in a position reflects the _______ of the residue in the alignment.

(a) height, relative frequency

(b) width, relative frequency

(c) height, amplitude

(d) width, amplitude

I have been asked this question in a national level competition.

The query is from Motif Discovery in Unaligned Sequences topic in chapter Sequence Alignment of Bioinformatics

Answer 1

The correct option is (a) height, relative frequency

For explanation: The height expresses the data about the extent of the conservation of the position and each letter shows the frequency of that particular residue. The amplitude, here in this case, is irrelevant option.
