In the early days of genomics, it seemed reasonable to believe that genes alone were the main actors in biology. They made proteins; proteins made cells; cells made organisms. When scientists began mapping genetic sequences in the 1970s and 1980s, they were astonished to find enormous stretches of D...

From Junk DNA: A Journey Through the Dark Matter of the Genome

If genes are the content of the book of life, enhancers, silencers, and promoters are its punctuation and rhythm. These elements determine not just what is said, but when, how loudly, and in what context. For decades, molecular biologists focused on coding sequences as the locus of function. But in ...

From Junk DNA: A Journey Through the Dark Matter of the Genome

For decades, the genome was thought to be life’s master blueprint. After Mendel’s elegant inheritance patterns and the elucidation of DNA’s structure, biologists believed they had found the ultimate code of life. But even as technology advanced—through the Human Genome Project and sequencing breakth...

From The Epigenetics Revolution: How Modern Biology Is Rewriting Our Understanding of Genetics, Disease and Inheritance

To understand epigenetic regulation, we must look at DNA not as a linear sequence but as a living structure. Inside the nucleus, two meters of DNA are packaged into chromatin—DNA wound around proteins called histones. Histones are more than spools; they are active players, modified by acetyl, methyl...
