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? ...

Study reveals key step in protein synthesis

Scientists at the University of California, Santa Cruz, have trapped the ribosome, a protein-building molecular machine essential to all life, in a key transitional state that has long eluded researchers. Now, for the first ...

DNA gridlock: Cells undo glitches to prevent mutations

Roughly six feet of DNA are packed into every human cell, so it is not surprising that our genetic material occasionally folds into odd shapes such as hairpins, crosses and clover leafs. But these structures can block the ...
