Cards

Term
Genetic Engineering
Definition
the group of applied techniques of genetics and biotechnology used to cut up and join together genetic material and especially DNA from one or more species of organism and to introduce the result into an organism in order to change one or more of its characteristics
Term
Vector
Definition
an organism that transmits a pathogen
Term
Recombiant DNA
Definition
genetically engineered DNA usually incorporating DNA from more than one species of organism
Term
Plasmids
Definition
an extrachromosomal ring of DNA especially of bacteria that replicates autonomously
Term
Restriction enzymes
Definition
 any of various enzymes that cleave DNA into fragments at specific sites in the interior of the molecule
Term
Gene cloning
Definition
Term
Screening
Definition
to test or examine for the presence of something
Term
Electrophoresis
Definition
 the movement of suspended particles through a medium (as paper or gel) under the action of an electromotive force applied to electrodes in contact with the suspension
Term
probes
Definition

a microprobe that uses an electron beam to induce X-ray emissions in a sample

Term
Vaccine
Definition
 a preparation of killed microorganisms, living attenuated organisms, or living fully virulent organisms that is administered to produce or artificially increase immunity to a particular disease
Term
Gene therapy
Definition
the insertion of usually genetically altered genes into cells especially to replace defective genes in the treatment of genetic disorders or to provide a specialized disease
Term
DNA fingerprint
Definition
a technique used especially for identification (as for forensic purposes) by extracting and identifying the base-pair pattern in an individual's DNA
Term
Human Genome Project
Definition
Term
Transgenic
Definition
 being or used to produce an organism or cell of one species into which one or more genes of another species have been incorporated
Term
Intron
Definition
a polynucleotide sequence in a nucleic acid that does not code information for protein synthesis and is removed before translation of messenger RNA
Term
Exon
Definition
 a polynucleotide sequence in a nucleic acid that codes information for protein synthesis and that is copied and spliced together with other such sequences to form messenger RNA
Term
Point Mutation
Definition
a gene mutation involving the substitution, addition, or deletion of a single nucleotide base
Term
Substitution
Definition
 the act, process, or result of substituting one thing for another
Term
Insertion
Definition
 the mutational process producing a genetic insertion
Term
Deletion
Definition
 the absence of a section of genetic material from a gene or chromosome
Term
Inversion
Definition
 a breaking off of a chromosome section and its subsequent reattachment in inverted position
Term
Translocation
Definition
transfer of part of a chromosome to a different position especially on a nonhomologous chromosome
Term
Clone
Definition
the aggregate of genetically identical cells or organisms asexually produced by a single progenitor cell or organism
Term
Karyotype
Definition
 the chromosomal characteristics of a cell; also : the chromosomes themselves or a representation of them
Term
Nondisjunction
Definition
 failure of homologous chromosomes or sister chromatids to separate subsequent to metaphase in meiosis or mitosis so that one daughter cell has both and the other neither of the chromosomes
