All the tissues in the human body are made from proteins, and for every protein, there's a stretch of DNA in the human genome that "codes" for it, or describes the sequence of amino acids that will produce it.

Many of us probably remember the punnett squares by which we were introduced to the idea of genetic inheritance in school: a dominant allele in each of my brown-eyed parents hides a recessive allele that explains my blue ...

A team of researchers with the University of California has found a way to show how historical contingencies constrained the evolution of a gene regulatory network. In their paper published in the journal Nature, the team ...
Understanding the molecular signals that guide early cells in the embryo to develop into different types of organs provides insight into how tissues regenerate and repair themselves. By knowing the principles that underlie ...
