Uptake signal sequence (USS) are short DNA sequences preferentially taken up by competent bacteria belonging to the Pasteurellacea family (e.g., Haemophilus influenzae). Similar sequences, called DNA uptake sequence (DUS), are found in species belonging to the Neisseriaceae family (including Neisseria meningitidis and Neisseria gonorrhoeae).
Famous quotes containing the words signal and/or sequence:
“Mistakes, scandals, and failures no longer signal catastrophe. The crucial thing is that they be made credible, and that the public be made aware of the efforts being expended in that direction. The “marketing” immunity of governments is similar to that of the major brands of washing powder.”
—Jean Baudrillard (b. 1929)
“We have defined a story as a narrative of events arranged in their time-sequence. A plot is also a narrative of events, the emphasis falling on causality. “The king died and then the queen died” is a story. “The king died, and then the queen died of grief” is a plot. The time sequence is preserved, but the sense of causality overshadows it.”
—E.M. (Edward Morgan)
