Summary
Genetic technology involves manipulating genes to create genetically modified organisms (GMOs) using techniques like recombinant DNA and genetic engineering. Microarrays and bioinformatics are tools used to analyze genetic information.
- Genetic Engineering — The process of altering the genetic material of an organism by inserting genes from another organism. Example: Creating insulin-producing bacteria by inserting the human insulin gene.
- Recombinant DNA (rDNA) — DNA that has been formed artificially by combining constituents from different organisms. Example: rDNA is used to create GMOs like transgenic plants.
- Microarrays — Tools used to study many genes at once and understand gene expression. Example: Comparing gene expression in healthy vs. diseased cells.
- Bioinformatics — The use of computer software to collect, process, and analyze biological data. Example: Analyzing genome sequences to find similarities between species.
