What's the difference between amplification and nomenclature?

Amplification


Definition:

  • (n.) The act of amplifying or enlarging in dimensions; enlargement; extension.
  • (n.) The enlarging of a simple statement by particularity of description, the use of epithets, etc., for rhetorical effect; diffuse narrative or description, or a dilating upon all the particulars of a subject.
  • (n.) The matter by which a statement is amplified; as, the subject was presented without amplifications.

Example Sentences:

  • (11) Polymerase chain reaction (PCR) amplification of cDNA confirmed this reduced level of DAF mRNA.
  • (12) Programmed gene rearrangements are used in nature to to alter gene copy number (gene amplification and deletion), to create diversity by reassorting gene segments (as in the formation of mammalian immunoglobulin genes), or to control the expression of a set of genes that code for the same function (such as surface antigens).

Nomenclature


Definition:

  • (n.) A name.
  • (n.) A vocabulary, dictionary, or glossary.
  • (n.) The technical names used in any particular branch of science or art, or by any school or individual; as, the nomenclature of botany or of chemistry; the nomenclature of Lavoisier and his associates.
