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.
Plant scientists have used a standard "gene gun" since 1988 to genetically modify crops for better yield, nutrition, pest resistance and other valuable traits.

Every day, our bodies perform around 330 billion cell divisions to keep us alive and functioning. These divisions rely on the cell cycle, which has been in place since the earliest bacteria. The principle is the same: double ...

Despite having identical genetic instructions, female honey bee larvae can develop into either long-lived reproductive queens or short-lived sterile workers who help rear their sisters rather than lay their own eggs. Now, ...

Understanding human biology requires more than mapping our genes—we must also understand how gene expression is regulated to guide healthy development, growth, and maintenance of our body systems over a lifetime.

We live in a world made and run by RNA, the equally important sibling of the genetic molecule DNA. In fact, evolutionary biologists hypothesize that RNA existed and self-replicated even before the appearance of DNA and the ...
