Note that the information content varies between 0 and 4.2 bits and signifies the overall sequence conservation for a particular cluster, while the sequence logo characterizes position specific residue conservation.
He will begin trying to build enthusiasm among some of the voters who propelled him to victory in 2008, like college students, while Democratic strategists are considering ways to turn the increased prominence of the Tea Party movement to their advantage by characterizing positions taken by some Tea Party-backed Republican candidates as extreme.
Yuan et al. [5] employed a Hidden Markov Model (HMM) to characterize positioned or delocalized nucleosomes.
To gain a better understanding of the sequence patterns that characterize positioned nucleosomes, we first performed an analysis of the periodicities of the 256 tetranucleotides in a yeast genome-wide library of nucleosomal DNA sequences that was prepared by in vitro reconstitution.
In contrast to simple sequence motifs of fixed length, i.e. position specific scoring matrices, pHMMs are suited for identifying motifs that are interrupted by segments of variable length, and are used to characterize position-specific sequence similarities within a family of proteins.
This is a very restricted approach since TREs can be very degenerated and, based on previously characterized TREs, position one (as well as other positions) could potentially have any of the four nucleotides.
Mr. Bush shot back, saying: "John, I don't appreciate the way you've characterized my position.
Correction: March 17, 2004, Wednesday A front-page headline yesterday about the views of Alan Greenspan, the Federal Reserve chairman, on debt levels in the United States characterized his position on budget deficits incorrectly.
Mr. Holbrooke declined to criticize Europe's commitment to the war in Afghanistan, rejecting such complaints as the "fruitless unproductive drama" that he said characterized the position of the Bush administration.
When the state of the system is fully characterized by position and momentum variables, the resulting space is often called phase space.
