Homological


Definition:

  • (a.) Pertaining to homology; having a structural affinity proceeding from, or base upon, that kind of relation termed homology.

  • (20) The most striking homology was to yeast SEC7 in the central domain of the gene (57% identical over 466 bp) and also the protein level (42% identical amino acids; 39% conserved amino acids).

Origin


Definition:

  • (n.) The first existence or beginning of anything; the birth.
  • (n.) That from which anything primarily proceeds; the fountain; the spring; the cause; the occasion.
  • (n.) The point of attachment or end of a muscle which is fixed during contraction; -- in contradistinction to insertion.

Example Sentences:
