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.
A new generation of CRISPR technology developed at UNSW Sydney offers a safer path to treating genetic diseases like sickle cell, while also proving beyond doubt that chemical tags on DNA—often thought to be little more ...

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 ...
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.

A new study that looked at gut length variation between cichlid fish species found that some of the genetic loci for the trait are sex-specific even though males and females of the same species have the same gut length. The ...
