Cell memory mechanism discovered

The cells in our bodies can divide as often as once every 24 hours, creating a new, identical copy. DNA binding proteins called transcription factors are required for maintaining cell identity. They ensure that daughter cells ...

A tighter fit with artificial DNA

An artificial base that enhances the protein-binding affinity and selectivity of DNA expands the DNA machinery.DNA aptamers are expected to play an important role in the diagnosis and treatment of various cancers and other ...

Decoding mystery sequences involved in gene regulation

Every cell in an organism's body has the same copy of DNA, yet different cells do different things; for example, some function as brain cells, while others form muscle tissue. How can the same DNA make different things happen? ...
