| Question | Answer |
|---|---|
| Bioinformatics | field of study that creates and maintains databases of biological information, especially genomic data. |
| Cloning | process in which large numbers of identical recombinant DNA molecules are produced. |
| DNA Fingerprinting | separating an individual’s unique sequence of DNA fragments to observe distinct banding patterns; can be used by forensic scientists to identify suspects and determine paternity. |
| DNA Ligase | enzyme that chemically links DNA fragments together. |
| DNA Microarray | silicon chips or microscope slides with DNA fragments that can allow many genes in a genome to be studied simultaneously |
| Gel Electrophoresis | process that involves using electric current to separate certain biological molecules by size |
| Gene Therapy | technique to correct mutated diseasecausing genes. |
| Genetic Engineering | technology used to manipulate an organism’s DNA by inserting the DNA of another organism |
| Genome | total DNA in each cell nucleus of an organism. |
| Genomics | study of an organism’s genome |
| Haplotype | area of linked genetic variations in the human genome |
| Inbreeding | selective breeding of closely related organisms to produce desired traits and eliminate undesired traits, resulting in pure lines—however, harmful recessive traits can also be passed on. |
| Pharmacogenomics | study of how genetic inheritance affects the body’s response to drugs in order to produce safer and more specific drug dosing |
| Plasmid | any of the small, circular, double-stranded DNA molecules that can be used as a vector |
| Polymerase Chain Reaction | genetic engineering technique that can make copies of specific regions of a DNA fragment. |
| Proteomics | study of the structure and function of proteins in the human body |
| Recombinant DNA | newly generated DNA fragment containing exogenous DNA |
| Restriction Enzyme | bacterial protein that cuts DNA into fragments. |
| Selective Breeding | directed breeding to produce plants and animals with desired traits |
| Single Nucleotide Polymorphism | variation in a DNA sequence occurring when a single nucleotide in a genome is altered. |
| Test Cross | breeding that can be used to determine an organism’s genotype |
| Transformation | process in which bacterial cells take up recombinant plasmid DNA |
| Transgenic Organism | organism that is genetically engineered by inserting a gene from another organism |
