Study of heredity and variation in living organisms.
Molecular genetics studies how genes are copied, read, and used in living cells.
The flow of genetic information is often summarized as:
\[ \text{DNA} \rightarrow \text{RNA} \rightarrow \text{Protein} \]
Knowing how genes work at a molecular level helps us understand diseases, develop new medicines, and engineer better crops.
Scientists can now edit genes using tools like CRISPR, opening up amazing possibilities—and important ethical questions!
\[\text{DNA} \rightarrow \text{RNA} \rightarrow \text{Protein}\]
Using CRISPR to correct a genetic mutation in lab mice.
Sickle-cell anemia is caused by a tiny change in the DNA code for hemoglobin.
Molecular genetics explains how genetic information is copied and used within cells.
