What's the difference between amplifier and tuner?

Amplifier


Definition:

  • (n.) One who or that which amplifies.

Example Sentences:

  • (13) HDV cDNA was then directly amplified with Taq polymerase using three pairs of specific primers.
  • (14) As an extension to the variety of existing techniques using polymorphic DNA markers, the Random Amplified Polymorphic DNA (RAPD) technique may be used in molecular ecology to determine taxonomic identity, assess kinship relationships, analyse mixed genome samples, and create specific probes.
  • (15) cDNA was prepared by reverse transcription of peripheral blood mRNA and amplified by the polymerase chain reaction (PCR) using primers corresponding to sequences 400 bp apart on the cDNA, spanning the last three exons (X, Y, Z) of the beta-Sp gene.
  • (16) Whether we would use that to support and amplify the community ideals already present or go the way of gentrification remained to be seen.
  • (17) Optimum specific amplification resulted when the primer annealing temperature was 60 degrees C. The gene fragment was amplifiable in 25 different Brucella species and strains.
  • (18) The action of exogenous etiologic agents is usually mediated in part or amplified by endogenous mediators that very often exert biphasic, i.e., damaging and protective, effects.
  • (19) By using primer 1 (5'-AAAGAATTCATGGAATCCAGGATCTG-3', upstream nucleotides 157 to 2877), primer 2 (5'-AAAGAATTCATGAACGTGAAGGAATCG-3', upstream nucleotides 1846 to 2877), and primer 4(5'-ATAAAGCTTAATCAGACGTTCTCTTCTTC-3', downstream nucleotides 157 to 2877 and 1846 to 2877), the HCMV B gene code region sequence and its glycoprotein 52 kd antigenic domain sequence were amplified from the recombinant plasmid pBH1 DNA containing the HCMV B gene.
  • (20) The PCR amplified a 375-bp DNA fragment which was cloned and sequenced; the deduced amino acid sequence had significant identity with known TS sequences, including strict conservation of all phylogenetically invariant TS amino acid residues.

Tuner


Definition:

  • (n.) One who tunes; especially, one whose occupation is to tune musical instruments.

Example Sentences:

  • (1) Kinetic analysis shows that this scheme reduces errors at 'hungry' codons considerably more effectively than J. Ninio's accuracy tuner model; for example, a 10-fold decrease in cognate aminoacyl-tRNA elicits only a 10% increase in the error frequency.
  • (2) Spearman's Rho correlations indicated that measures taken with the autochromatic tuner significantly correlated with measures taken with the other instruments.
  • (3) One transmits at 100 MHz and its signal can be received on a standard FM tuner.
  • (4) Hence, the pineal gland may function as a "fine tuner" of calcium homeostasis.
  • (5) Each receiver consists of a demodulator, a channel selectable tuner, and a video monitor.
  • (6) On the basis of the results, a role is attributed to the decreased growth hormone reserve in the low growth of Tuner's syndrome patients.
  • (7) Thus the modulator may function as a biologic "fine tuner" providing on additional mechanism by which the signals imparted to cells by physiologic stimuli can be correctly expressed.
  • (8) It is no longer enough simply to play music (or, as non-iPod devices often can, have an FM tuner and voice recorder).
