words only definitions & notes
  1. 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.
  2. 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.
  3. recessive allele
    an allele that produces its characteristic phenotype only when its paired allele is identical
    On the other hand, a recessive allele will be expressed only if there are two identical copies of that allele, or for a male, if one copy is present on the X chromosome.
  4. prokaryote
    a unicellular organism lacking a membrane-bound nucleus
    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.
  5. phenotype
    observable characteristics produced by genes and environment
    When two individuals display different phenotypes of the same trait, they are said to have two different alleles for the same gene.
  6. 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.
  7. mitochondrion
    part of a cell involved in energy production
    Organelle DNA

    Not all genetic information is found in nuclear DNA. Both plants and animals have an organelle-a "little organ" within the cell- called the mitochondrion.
  8. ribosome
    a particle in a cell that helps synthesize proteins
    Because mitochondria have their own DNA, RNA, and ribosomes, this scenario is quite possible.
  9. meiosis
    cell division that produces reproductive cells
    Meiosis is the mode of cell replication for the formation of sperm and egg cells in plants, animals, and many other multicellular life forms.
  10. homozygous
    having identical alleles at corresponding chromosomal loci
    If both alleles are the same, the gene is said to be homozygous.
  11. chromosome
    a threadlike strand of DNA that carries genes
    In 1909, Danish botanist Wilhelm Johanssen coined the word gene for the hereditary unit found on a chromosome.
  12. hemoglobin
    a red protein in blood that transports oxygen
    Globin is the protein that complexes with the iron-containing heme molecule to make hemoglobin.
  13. melanin
    insoluble pigments that account for the color of e.g. skin and scales and feathers
    If a mutation affecting melanin production occurred in one of the cells in the cell lineage of one eye but not the other, then the eyes would have different genetic potential for melanin synthesis.
  14. sickle cell
    an abnormal red blood cell that has a crescent shape and an abnormal form of hemoglobin
    Examples of recessive disorders in humans include sickle cell anemia, Tay-Sachs disease, and phenylketonuria (PKU).
  15. dominant
    most frequent or common
    These factors each exhibit a characteristic dominant, co-dominant, or recessive expression, and those that are dominant will mask the expression of those that are recessive.
  16. bone marrow
    the fatty network of connective tissue that fills the cavities of bones
    By birth, red blood cells are being produced, and globin is expressed in the bone marrow.
