Word: Genetic Engineering
Definition:
Genetic engineering is a scientific process that allows scientists to change the DNA of living organisms. DNA is the material that contains the instructions for how an organism grows and functions. In genetic engineering, scientists can take pieces of DNA from one organism and combine them with DNA from another organism. This can be done to create new traits or characteristics in plants, animals, or even humans.
Usage Instructions:
- This term is used in scientific contexts, particularly in biology and biotechnology. - It is a noun, so you can use it as the subject or object in a sentence.
Example Sentence:
"The scientists used genetic engineering to create a new type of corn that is resistant to pests."
Advanced Usage:
In advanced discussions, you might encounter phrases like "recombinant DNA technology," which refers to the specific techniques used in genetic engineering to combine DNA from different sources. Scientists may also discuss "gene therapy," a form of genetic engineering that aims to treat diseases by altering the genes inside a person's cells.
Word Variants:
- Genetic Engineer (noun): A person who specializes in genetic engineering. - Genetics (noun): The study of genes and heredity. - Genetically (adverb): In a way that relates to genes or heredity.
Different Meanings:
While "genetic engineering" primarily refers to the scientific process, in broader discussions, it can also touch on ethical and social issues, such as the implications of modifying living organisms.
Synonyms:
- Gene manipulation - Gene editing - Biotechnology
Idioms and Phrasal Verbs:
While "genetic engineering" does not have specific idioms or phrasal verbs associated with it, discussions around it might include phrases like "crossing the line," which can refer to ethical concerns about how far genetic engineering should go.
Conclusion:
Genetic engineering is an important and powerful technology that allows us to understand and modify life at the molecular level.
