cells
t
tissue that surrounds and protects the content of a cell from the external environment
cell membrane
t
material within the cell membrane that is not part of the nucleus
cytoplasm
t
controls the activities of the cell and helps the cell divide
nucleus
t
unspecialized cells that are able to renew themselves for long periods of time by cell division
stem cell
t
(somatic stem cells) undifferentiated cells found among differentiated cells in the tissue or organ
adult stem cells
t
adult stem cells that have the ability to form any adult cell
embryonic stem cells
t
fundamental physical and functional unit of heredity
gene
t
complete set of genetic information of an organism
genome
t
a genetic structure of located within the nucleus of each cell
chromosome
t
any cell in the body except the gametes
somatic cell
t
(sex cell) only cell that does not contain 46 chromosomes
gamete cell
t
a change of the sequence of a DNA molecule
genetic mutation
t
change within the cells of the body
somatic cell mutation
t
change within the genes in a gamete that can be transmitted by a parent to his or her children
gametic cell mutation
t
manipulating or splicing of genes for scientific or medical purposes
genetic engineering
t
(hereditary disorder) pathological condition caused by an absent or defective gene
genetic disorder
t
(CF) a genetic disorder that is present at birth and affects both the respiratory and digestive systems

t
(DS) a genetic variation that is associated with a characteristic facial appearance, learning disabilities, developmental delays, and physical abnormalities such as heart valve disease
Down Syndrome
t
a group of hereditary bleeding disorders in which a blood-clotting factor is missing
