For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...

Alan Herbert, Founder and President of InsideOutBio, discusses the evolution of biological concepts related to DNA and protein structures ...

New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

DNA is the molecule that holds the instructions for all living things. DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Check your ...

Revising the structure and replication of DNA? Test your knowledge of the process and need for DNA replication with this Higher Biology quiz.

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible to the cellular machinery that works to express the right genes at the ...

Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily.

Researchers in Japan have identified a striking new way immune cells strip DNA out of dying neighbors, a process they call ...

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.
