Genetics is the branch of biological sciences that investigates the organization, transmission, variation, and functional consequences of hereditary information in organisms. It focuses on the structure and function of genes and genomes, the molecular mechanisms of DNA replication, transcription, and translation, and the regulation of gene expression across developmental and environmental contexts. Genetics encompasses classical (Mendelian) inheritance, molecular genetics, population and quantitative genetics, and genomics, providing the framework for understanding mutation, recombination, genetic linkage, and evolutionary change, as well as informing experimental design and interpretation in biomedical, agricultural, and model-organism research.
Plants may be stuck in one place, but the world around them is constantly changing. In order to grow and flower at the right time, plants must constantly collect information about their surroundings, measuring things like ...

For decades, the central dogma of molecular biology—DNA makes RNA, RNA makes protein, protein makes phenotype—was the guiding framework for understanding inheritance and disease. This model explained classic Mendelian traits, ...
When people think of DNA, they usually think of genes, the parts that code for proteins and drive inherited traits. But there's a whole lot of DNA beyond genes that we are just starting to understand. One such mysterious ...
A new genomic study reveals how human populations adapted, survived, and diversified in the Himalayas, one of the most extreme and challenging environments on Earth.
