What's the difference between extraction and extrusion?

Extraction


Definition:

  • (n.) The act of extracting, or drawing out; as, the extraction of a tooth, of a bone or an arrow from the body, of a stump from earth, of a passage from a book, of an essence or tincture.
  • (n.) Derivation from a stock or family; lineage; descent; birth; the stock from which one has descended.
  • (n.) That which is extracted; extract; essence.

Example Sentences:

  • (20) Sequence specific binding of protein extracts from 13 different yeast species to three oligonucleotide probes and two points mutants derived from Saccharomyces cerevisiae DNA binding proteins were tested using mobility shift assays.

Extrusion


Definition:

  • (n.) The act of thrusting or pushing out; a driving out; expulsion.

Example Sentences:
