How cells hack their own genes

DNA in all organisms from yeast to humans encodes the genes that make it possible to live and reproduce. But these beneficial genes make up only 2 percent of our DNA. In fact, more than two-thirds of our genome is populated ...

In fruit fly and human genetics, timing is everything

Every animal starts as a clump of cells, which over time multiply and mature into many different types of cells, tissues, and organs. This is fundamental biology. Yet, the details of this process remain largely mysterious. ...

Plant genes may lack off switch, but have volume control

Scientists at the University of California, Davis have discovered that DNA sequences thought to be essential for gene activity can be expendable. Sequences once called junk sometimes call the shots instead.

Scientists reveal hidden structures in bacterial DNA

DNA contains the instructions for life, encoded within genes. Within all cells, DNA is organised into very long lengths known as chromosomes. In animal and plant cells these are double-ended, like pieces of string or shoelaces, ...
