words only definitions & notes
  1. diploid
    an organism or cell having the normal amount of DNA per cell
    The term diploid describes a state in which a cell has two sets of homologous chromosomes, or two chromosomes that are the same.
  2. centromere
    a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape
    The most highly repeated sequences found so far in mammals are called "satellite DNA" because their unusual composition allows them to be easily separated from other DNA. These sequences are associated with chromosome structure and are found at the centromeres (or centers) and telomeres (ends) of chromosomes.
  3. phenotypic
    of or relating to or constituting a phenotype
    These expressed, or phenotypic, traits are attributable to genotypic variation in a person's DNA sequence.
  4. genotypic
    of or relating to or constituting a genotype
    These expressed, or phenotypic, traits are attributable to genotypic variation in a person's DNA sequence.
  5. 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.
  6. pyrimidine
    a heterocyclic organic compound with a penetrating odor
    A DNA chain is made up of four chemical bases: adenine (A) and guanine (G), which are called purines, and cytosine (C) and thymine (T), referred to as pyrimidines.
