definitions & notes only words
  1. allele
    any of the forms of a gene that can occupy the same locus
    Methylation also plays an important role in genomic imprinting, which occurs when both maternal and paternal alleles are present but only one allele is expressed while the other remains inactive.
  2. eukaryote
    an organism of one or more cells with membrane-bound nuclei
    The location and base sequence of each promoter site vary for prokaryotes (bacteria) and eukaryotes (higher organisms), but they are both recognized by RNA polymerase, which can then grab hold of the sequence and drive the production of an mRNA.
