  • Q1
    A change in the structure of a chromosome
    Chromosomal Mutation
  • Q2
    The loss of a segment of a chromosome and thus a loss of a segment containing genes
  • Q3
    When a segment of a chromosome is duplicated and thus displayed more than once on a chromosome
  • Q4
    When a segment of a chromosome breaks off and reattaches in reverse order
  • Q5
    When a segment of one chromosome breaks off and attaches to a nonhomologous chromosone
  • Q6
    A process in which a cell, cell product, or organism is copied from an original source
  • Q7
    the transfer of a DNA fragment from one organism to a self-replicating genetic element such as a bacterial plasmid
    DNA Cloning
  • Q8
    The transfer of genetic material from the nucleus of a donor adult cell to an egg cell that has had its nucleus removed for the purpose of creating an embryo that can produce an exact genetic copy of the donor organism
    Reproductive Cloning
  • Q9
    The process of taking undifferentiated embryonic cells (STEM cells) for use in medical research
    Therapeutic Cloning
  • Q10
    A pattern of inheritance in which the phenotypic effect of two alleles in a heterozygous genotype express each phenotype of each allele fully and equally; a phenotype which would not be expressed in any other genetic combination
  • Q11
    An exchange of genetic material between homologous chromosomes during Anaphase 1 of meiosis; contributes to genetic variability in gametes and ultimately in offspring
    Crossing Over
  • Q12
    A pattern of inheritance in which the phenotypic effect of one allele is completely expressed within a homozygous and heterozygous genotype
    Dominant Inheritance
  • Q13
    The addition (insertion) or removal (deletion) of one or more nucleotides that is not indivisible by three, therefore resulting in a completely different amino acid sequence than would be normal.
    Frame-Shift Mutation
  • Q14
    A natural process in which a nucleic acid molecule (usuallyDNA but can be RNA) is broken and then joined to a different molecule; a result of crossing-over
    Gene Recombination
  • Q15
    A type of gene recombination in which the DNA is intentionally broken and recombined using laboratory techniques
    Gene Splicing
