Question

Gibbs is a web-based program that uses the Gibbs sampling approach to look for _____ gap-free segments for either DNA or protein sequences.

(a) short, partially conserved

(b) long, partially conserved

(c) long, conserved

(d) short, not conserved

The question was asked in quiz.

My question is taken from Motif Discovery in Unaligned Sequences in portion Sequence Alignment of Bioinformatics

Answer 1

Right choice is (a) short, partially conserved

To explain I would say: Gibbs sampling approach to look for short, partially conserved gap-free segments for either DNA or protein sequences. To ensure accuracy, more than twenty sequences of the exact same length should be used.
