The Y chromosome is inherited only through the paternal line. Sons receive their Y chromosome exclusively from their father.
Learning to read and write is the beginning of literacy, a progression now mirrored in modern genomics. Scientists first read the human genome, a three-billion-letter biological book, in April 2003.
Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...
A study of artificial human and chimpanzee nerve cells revealed how faster-evolving DNA gives neurons the ability to build increasingly complex brain power How did humans evolve brains capable of ...
Scientists have achieved a genetic feat once thought impossible: removing an entire extra human chromosome using gene-editing ...
