  1. Metaphase
    The third subphase of mitosis, in which the spindle is complete and the chromosomes, attached to microtubules at their kinetochores, are all aligned at the metaphase plate.
  2. Fatty acid
    A long carbon chain carboxylic acid. Fatty acids vary in length and in the number and location of double bonds; three fatty acids linked to a glycerol molecule form fat.
  3. Peroxisome
    A microbody containing enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen peroxide.
  4. Null hypothesis
    A hypothesis expressed in the negative to avoid accusation of bias.
  5. Corepressor
    A molecule (e.g. tryptophan) that binds to an allosteric repressor protein and enables it to prevent transcription.
  6. Mitotic spindle
    An assemblage of microtubules and associated proteins that is involved in the movements of chromosomes during mitosis.
  7. Hydrophobic
    Having an aversion to water; tending to coalesce and form droplets in water.
  8. Golgi apparatus
    An organelle in eukaryotic cells consisting of stacks of flat membranous sacs that modify, store, and route products of the endoplasmic reticulum.
  9. Antisense
    The name given to a nucleic acid strand that is complementary to mRNA or the DNA coding strand.
  10. Ribonucleic acid (RNA)
    A type of nucleic acid consisting of nucleotide monomers with a ribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and uracil (U); usually single-stranded; functions in protein synthesis and as the genome of some viruses.
