(Phys.org)—Gene expression plays a central role in the orchestration of virtually all cellular processes. While inducible promoters have proven invaluable in understanding regulatory networks by modifying gene expression ...
It was long thought that methylation, a crucial part of normal organism development, was a static modification of DNA that could not be altered by environmental conditions. New findings by researchers at the Salk Institute ...

As an embryo develops, different genes are turned on in different cells, to form muscles, neurons and other bodily parts. Inside each cell's nucleus, genetic sequences known as enhancers act like remote controls, switching ...

When a sperm fertilizes an egg, each contributes a set of chromosomes to the resulting embryo, which at these very early stages is called a zygote. Early on, zygotic genes are inert, so embryonic development is largely controlled ...
