What's the difference between crinkle and null?

Crinkle


Definition:

  • (v. t.) To form with short turns, bends, or wrinkles; to mold into inequalities or sinuosities; to cause to wrinkle or curl.
  • (v. i.) To turn or wind; to run in and out in many short bends or turns; to curl; to run in waves; to wrinkle; also, to rustle, as stiff cloth when moved.
  • (n.) A winding or turn; wrinkle; sinuosity.

  • (20) A short open reading frame (ORF), ORF6, potentially encoding a polypeptide (pX) of 32-69 amino acids, was revealed upon computer translation of the 3' terminal regions of tomato bushy stunt, cymbidium ringspot, cucumber necrosis and artichoke mottled crinkle tombusviruses.

Null


Definition:

  • (n.) Something that has no force or meaning.
  • (n.) That which has no value; a cipher; zero.
  • (v. t.) To annul.
  • (n.) One of the beads in nulled work.
