Terminal


Definition:

  • (n.) Of or pertaining to the end or extremity; forming the extremity; as, a terminal edge.
  • (n.) Growing at the end of a branch or stem; terminating; as, a terminal bud, flower, or spike.
  • (n.) That which terminates or ends; termination; extremity.
  • (n.) Either of the ends of the conducting circuit of an electrical apparatus, as an inductorium, dynamo, or electric motor, usually provided with binding screws for the attachment of wires by which a current may be conveyed into or from the machine; a pole.

Example Sentences:

  • (1) The amino acid sequence deduced from the nucleotide sequence contained both amino- and carboxyl-terminal sequences.
  • (2) Treatment termination due to lack of efficacy or combined insufficient therapeutic response and toxicity proved to be influenced by the initial disease activity and by the rank order of prescription.
  • (3) We have examined the insertion of bovine 17 alpha-hydroxylase (P45017 alpha) into the endoplasmic reticulum of COS 1 cells to evaluate the functional role of its hydrophobic amino-terminal sequence and membrane insertion.

  • (6) Plasma NPY correlated better with plasma norepinephrine than with epinephrine, indicating its origin from sympathetic nerve terminals.
  • (7) As a group, the three mammalian proteins resemble bovine serum conglutinin and behave as lectins with rather broad sugar specificities directed at certain non-reducing terminal N-acetylglucosamine, mannose, glucose and fucose residues, but with subtle differences in fine specificities.
  • (8) In the caudal spinal trigeminal nucleus (Vc), the collaterals of one half of the periodontium afferent fibers terminated mainly in lamina V at the rostral and middle levels of Vc.
  • (9) The amino-terminal region of a 70 kDa mitochondrial outer membrane protein of yeast and the presequence of cytochrome c1, an inner membrane protein exposed to the intermembrane space, are thought to be responsible for localizing the proteins in their final destinations after synthesis in the cytosol.
  • (10) The mtRF-1 could translate all of the known termination codons in the rat mitochondrial genome.
  • (11) However, none of the nerve terminals making synaptic contacts with glomus cells exhibited SP-like immunoreactivity.
