What Do You Know

  1. Where is your DNA?
    only in your gonads
    in all your cells
    only in your blood

  2. Who has the exact same DNA as you do?
    all human beings
    your children
    only you

  3. What is a gene?
    the basic unit of hereditary information
    a cell in the human body that causes disease
    a protein found in the human body

  4. What is a genome?
    the part of a cell that makes proteins
    an organism's complete set of hereditary information
    all the cells in an organism

  5. What's the relationship between genes and chromosomes?
    Genes are found in every cell; chromosomes are found only in sex cells.
    Chromosomes determine gender; genes determine other cellular functions.
    Chromosomes are compact storage units for genes.

  6. What is the main goal of the Human Genome Project?
    to eliminate the genes that cause disease in humans
    to determine the complete set of hereditary information present in humans
    to enable us to genetically engineer and clone human beings

  7. How many genes does the human genome contain?
    forty-six
    between 30,000 and 80,000
    three billion

  8. If you have a gene for a disease, will you get that disease?
    yes
    only if both your parents have the gene
    it depends

  9. How much of your DNA is needed in order to conduct a genetic test?
    a single cell
    a teaspoon
    a tissue sample

  10. What conditions can currently be genetically tested for?
    only single-gene-linked diseases like Tay-Sachs, Huntington's, and Down's syndrome
    certain cancers, including breast, ovarian, and colon
    both 1 and 2

  11. Genetic technologies can enable humans to:
    engineer a race of physically superior beings
    know the gender and some basic health information about a fetus
    create babies with pre-selected traits

  12. What is the link between genes and complex social behaviors such as shyness or intelligence?
    Behavior can represent a complex link between genes and environment.
    Genes determine specific behaviors in every individual.
    Genes have no influence on behavior, only on physical traits.
