Amniocentesis

a medical procedure in which a sample of cells from the amniotic fluid is tested for abnormalities in a fetus

Chorionic Villi Sampling

sampling of cells from the chorion to test for genetic conditions in a fetus. The cells are grown in a special medium after which a karotype can be used to make a diagnosis.

Fetoscopy

enables direct observation of the fetus through an endoscope to allow medical professionals to safely perform various procedures directly inside the womb

Genetic Markers

any characteristic that provides information about an organism's genome

Gel Electrophoresis

can be used to generate a DNA fingerprint.

Prenatal diagnoses

____________ can be used to determine some genetic conditions and disorders

Gene therapy

_______________ is being tested as one way to reverse some of the effects of genetic disorders

GMOs

Genetically modified organisms

GMFs

Genetically modified foods

Chorionic Villi Sampling

Used to test for genetic defects and can be done as early as the ninth week of pregnancy

Restriction Enzymes

enzymes which recognize a specific short sequence of nucleotides (the target sequence) on a strand of DNA and cut the strand at a particular point within that sequence

Recombinant DNA

segments of DNA from two different species that are joined in a laboratory to form a single molecule of DNA

Polymerase Chain Reaction

almost entirely automated method of replicating DNA that allows researchers to target and amplify a very specific sequence within a DNA sample

Cloning

a process in which an identical copy of an organism or part of an organism that has the same genetic make-up, such as the offspring of asexual reproduction, a general term for the research activity that creates a copy of some biological entity (a gene or organism or cell)

Human Genome Project

Determined the sequence of three billion base pairs that make up the human genome

Restriction Site

the specific sites at which a restriction enzyme will cleave DNA
