Molecular Genetics
Definition:
Molecular genetics is a branch of science that studies genes and genetic information at a very small, or molecular, level. It looks at how genes are structured and how they work. This field helps us understand how traits are passed from parents to children and how DNA (the material that makes up our genes) functions.
Usage Instructions:
- Part of Speech: Noun (it is always used as a singular or plural noun) - To use "molecular genetics" in a sentence, you might say: "Molecular genetics helps scientists understand diseases better."
Example Sentence:
"The researchers in the lab are focusing on molecular genetics to find out how certain genetic mutations cause illnesses."
Advanced Usage:
In more advanced discussions, you might see molecular genetics mentioned in the context of genetic engineering, where scientists manipulate genes to create desirable traits in organisms or develop new medical treatments.
Word Variants:
- Molecular Geneticist: A scientist who specializes in molecular genetics. - Molecular Genetic: An adjective describing something related to molecular genetics, e.g., molecular genetic research.
Different Meanings:
While "molecular genetics" specifically refers to the study of genes at a molecular level, "genetics" on its own can refer to the broader study of heredity and variation in organisms, not just at the molecular level.
Synonyms:
- Genetic biology - Biogenetics (though this term is less common)
Idioms and Phrasal Verbs:
There are no specific idioms or phrasal verbs directly related to "molecular genetics," but you might encounter terms like "break down" (to analyze) when discussing the components of genes or genetic processes.
Summary:
Molecular genetics is an important field that helps us understand how our genes work and how they affect our health and traits.
