inexpensive to grow in large quantities, self-repair more efficiently, methods for gene transfer and expression are well established for this plant because long history of plant breeding
Term
what are the 3 R's in animal research?
Definition
Replace: the use of animals with alternative techniques or avoid animals altogether

Reduce: the number of animals to a minimum that are tested.

Refine: the way that experiments are carried out to make sure animals suffer as little as possible.
Term
what are two alternatives to animal models?
Definition
1 in vitro cell culture techniques
2 in silico computer simulations
Term
what are shortcoming of alternative animal models?
Definition
cultured cells involve animal derived products such as serum

simulations use data from previous animal experiments

rapid growth visible, eggs accept gene transfer readily, transparent embryos,
Term
Antibody secreting tumors?
Definition
myeloma
Term
gene from one organism introduced into another organism to create a trangenic; term usually applies to genes used to create transgenic animals and lpants
Definition
transgene
Term
an active gene is replaced with DNA that has no functional information
Definition
knock out
Term
splitting embryos in half at the two cell stage of development to produce two embryos

apoptosis
Term
substances used as indicators of a biologic state objectively measured and evaluated as an indicator of normal processes, patho proc, or pharm responses to therapy intervention
Definition
biomarkers
Term
a chip consistng of a glass microscop slide containing thousands of pieces of single stranded dna molecules atached to specific spots on the slite; each spot of dna is a unique sequence
Definition
microarray
Term

tissues engineering
Term
cellular aging process
Definition
senescence
Term
hollow cluter of approximatey 100 cells formed about 1 week after fertilization of an egg
Definition
blastocyst
Term
creating an embryo without fertilization by pausing DNA division in an egg and allowing the egg to develop with an increased number of chromosomes; for instance, preventing chromosomes from separating in a human egg creates a diploid cell that may develop to form an embryo.
Definition
parthenogenesis
Term

what is a gene?
Definition
a specific sequence of DNA nucleotides that serves as a unit of inheritance
Term
lab technique that uses single stranded dna or rna probes labeled with fluorescent nuc to identify gene sequences ina chromosome or sel in situ
Definition
fish hybridization
