Mutations and Genetic Engineering
| Question | Answer |
|---|---|
| error in meiosis in which homologous chromosomes fail to separate | non-disjunction |
| a part of DNA from a chromosome is lost | deletion |
| any change in a DNA sequence | mutation |
| the order of the genes in a section of a chromosome is reversed and reattached to the same chromosome | inversion |
| a part of chromosome is repeated | duplication |
| the order of the genes in a section of a chromosome is reversed and reattached to a different chromosome | translocation |
| a mutation in which one or just a few nucleotides in a gene are changed | point muatation |
| a mutation in which one or just a few nucleotides in a gene are changed | substitution |
| a mutation that affects the reading frame because of an addition or subtraction of a nucleotide | frameshift |
| a research effort to sequence and locate the entire collection of genes in human cells | human genome project |
| DNA produced by combining DNA from different sources | recombinant DNA |
| enzyme that cuts DNA at a specific sequence of nucleotides | restriction enzyme |
| making a genetically identical copy of DNA or of an organism | cloning |
| a form of applied genetics in which scientists directly manipulate genes | genetic engineering |
| a pattern of bands made up of specific fragments from an individual's DNA | DNA fingerprint |
| technique used to separate nucleic acids or proteins by size and charge | gel electrophoresis |
| treatment of a genetic disorder by introducing a healthy gene into a cell | gene therapy |
| genetically modified organism; a host organism that has received recombinant DNA | GMO; transgenic organism |
| technique used to quickly make many copies of selected segments of DNA | polymerase chain reaction (PCR) |
| when parents are chosen based on their traits | selective breeding |
| unspecialized cells that retain the ability to become a wide variety of specialized cells | stem cell |
