Full list of words from this list:

  1. eukaryotic
    having cells with `good' or membrane-bound nuclei
    This theory is also supported by the existence of a eukaryotic organism, called the amoeba, which lacks mitochondria.
  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. ribose
    a pentose sugar important as a component of ribonucleic acid
    However, the ribose sugar component of RNA is slightly different chemically than that of DNA. RNA has a 2' oxygen atom that is not present in DNA. Other fundamental structural differences exist.
  5. allelic
    of or relating to alleles
    Determining the allelic condition used to be accomplished solely through the analysis of pedigrees, much the way Mendel carried out his experiments on peas.
