Amniocentesis - A technique for determining genetic abnormalities in a fetus by the presence of certain chemicals or defective fetal cells in the amniotic fluid, obtained by aspiration from a needle inserted into the uterus
Anneal - To be capable of combining with complementary nucleic acid by a process of heating and cooling.
Carrier Screening - Indiscriminate examination of members of a population to detect heterozygotes for serious disorders.
Chorionic Villus Sampling (CVS) - A technique for diagnosing genetic and congenital defects in a fetus by removing and analyzing a sample of the fetal portion of the placenta.
Cloning - The process of creating a genetically identical copy through growing identical cells in vitro or the transplantation of a somatic cell nucleus etc.
Denaturation - The first step in DNA amplification and in DNA, the separation of the two strands of the double helix.
Gene - A discrete unit of hereditary information consisting of a specific nucleotide sequence of DNA.
Gene Therapy - An experimental technique that uses genes to treat or prevent disease.
This is only one example of gene therapy: Gene Augmentation Therapy
Genetic Counseling - A process of communication that deals with the occurrence or risk that a genetic disorder will occur in a family.
Genetic Testing- The use of methods to determine if someone has a genetic disorder, will develop one, or is a carrier
Genome - The complement of an organism’s genes; an organisms genetic material.
Genotype - It is a person's complete heritable genetic identity and can be used to refer to particular genes.
In Vitro Fertilization - It is an assisted reproductive technology, It is the process of fertilization by manually combining an egg and sperm in a laboratory dish, and then transferring the embryo to the uterus
Karyotype - A display of the chromosome pairs of a cell arranged by size and shape.
Newborn Screening - The analysis of a neonate's blood for metabolic or genetic disorders to prevent mental retardation, disability or death.
Phenotype - The physical and physiological traits of an organism.
Polymerase Chain Reaction - A technique that involves copying short pieces of DNA and then making millions of copies in a short period of time.
Preimplantation Genetic Diagnosis PGD - In assisted reproductive technology, the determination of genetic abnormalities in the embryo before it is transferred to the uterus.
Primer - A short piece of DNA or RNA that is complementary to a section of template strand and acts as an attachment and starting point for the synthesis strand during DNA replication.
Restriction Enzyme - A degradative enzyme that recognizes specific nucleotide sequences and cuts up DNA.
Sex Selection - refers to the practice of using medical techniques like,selecting embyros for transfer, IVF, separating sperm, to choose the sex of offspring
Single Nucleotide Polymorphism (SMP) - One base-pair variation in the genome sequence.
Supernatant - The (usually) clear liquid left behind after a precipitate has been spun down to the bottom of a vessel by centrifugation.
Taq Polymerase - A DNA synthesis enzyme that can withstand the high temperatures of PCR.
Thermal Cycler - An instrument that automatically cycles through different temperatures used to complete PCR reactions
Ultrasonography - A noninvasive technique involving the formation of a two-dimensional image used for the examination and measurement of internal body structures and the detection of bodily abnormalities.
