RNA Binding Proteins: Mystery Sequences Involved In Gene Regulation Decoded

Every cell in an organism's body has the same copy of DNA, though different cells do different things so some function as brain cells, while others form muscle tissue. How can the same DNA make different things happen? Science is a step closer to ans ...

Molecular Monkey Sometimes Throws A Wrench Into X-chromosome Activation

X chromosomes are special, even for genetic material. They differ in number between men and women and to achieve equality between sexes, one out of two X chromosomes in women is silenced. In Drosophila, the opposite happens: in male flies, the only availa ...
