Where is your DNA?
only in your gonads
in all your cells
only in your blood
Who has the exact same DNA as you do?
all human beings
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
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
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.
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
How many genes does the human genome contain?
between 30,000 and 80,000
If you have a gene for a disease, will you get that disease?
only if both your parents have the gene
How much of your DNA is needed in order to conduct a genetic test?
a single cell
a tissue sample
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
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
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.
