| signature | 1. A sign, stamp, or mark impressed, as by a seal. "The brain, being well furnished with various traces, signatures, and images." (I. Watts) "The natural and indelible signature of God, which human souls . . . Are supposed to be stamped with." (Bentley) 2. Especially, the name of any person, written with his own hand, employed to signify that the writing which precedes accords with his wishes or intentions; a sign manual; an autograph. 3. <physiology> An outward mark by which internal characteristics were supposed to be indicated. "Some plants bear a very evident signature of their nature and use." (Dr. H. More) 4. <medicine> A resemblance between the external characters of a disease and those of some physical agent, for instance, that existing between the red skin of scarlet fever and a red cloth; supposed to indicate this agent in the treatment of the disease. 5. The designation of the key (when not C major, or its relative, A minor) by means of one or more sharps or flats at the beginning of the staff, immediately after the clef, affecting all notes of the same letter throughout the piece or movement. Each minor key has the same signature as its relative major. 6. A letter or figure placed at the bottom of the first page of each sheet of a book or pamphlet, as a direction to the binder in arranging and folding the sheets. The printed sheet so marked, or the form from which it is printed; as, to reprint one or more signatures. Star signatures (as A, 1) are the same characters, with the addition of asterisks, used on the first pages of offcuts, as in 12mo sheets. 7. <pharmacology> That part of a prescription which contains the directions to the patient. It is usually prefaced by S or Sig. (an abbreviation for the Latin signa, imperative of signare to sign or mark). Origin: F. (cf. It. Signatura, segnatura, Sp. & LL. Signatura), from L. Signare, signatum. See Sign. Source: Websters Dictionary (01 Mar 1998) |

| signal peptide |
A signal peptide is a short (15-60 amino acids long) peptide chain that directs the post translational transport of a protein. Some signal peptides are cleaved from the protein by signal peptidase after the proteins are transported. Signal peptides may also be called targeting signals or signal sequences. ...

| signal-to-noise ratio |
(Abbreviated SNR.) A ratio that measures the information content of a signal, usually defined as the ratio of the power of the signal unaffected by noise to the power of the noise. Commonly measured in decibels, the signal-to-noise ratio is sometimes defined for a specified bandwidth.
