Scientists found that some inherited traits can bypass the traditional rules of genetics, revealing a surprising new layer of ...
A research team led by Professor Yuanliang ZHAI at the School of Biological Sciences, The University of Hong Kong (HKU) collaborating with Professor Ning GAO and Professor Qing LI from Peking ...
When we think about genetic inheritance, we usually leap to DNA, the four-letter code containing the instructions for building a living organism. Scientists know that DNA encodes everything from hair ...
Srinivasu Karri is a postdoctoral researcher at the University of Minnesota. He investigates how cells accurately recycle parental histones during DNA replication to maintain critical chromatin states ...
Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...
If parent cells and their daughter cells are to share a stable identity, parent cells must divide—and replicate their DNA—while ensuring that their histones are distributed properly to their daughter ...
Scientists uncovered DNA's double helix structure in 1953. James Watson and Francis Crick proposed the model. It explained ...
DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on, it must be acted upon by an enzyme called RNA polymerase. This is a molecular machine which ...
On his son’s fourth birthday, Michael Prescott had his first heart attack. Prescott, who worked as a civil engineer designing bridges in Tennessee, was in his 30s, and until that day, he had appeared ...
