Each baby girl starts out with two X chromosomes, but to be healthy she only needs the genes from one. The extra X chromosome gets trussed up and shut down in the earliest stages of development.
Scientists have been manipulating genes for a while. The University of Pittsburgh's Alexander Deiters just found a way to control the process with higher precision.
One of developmental biology's most perplexing questions concerns what signals transform masses of undifferentiated cells into tremendously complex organisms, a process called ontogeny.
Researchers have discovered a new gene that enables plants to regulate their growth in different temperatures.
Scientists at the University of Chicago, Harvard, and China have described the surprising discovery and function of a new DNA modification in insects, worms, and algae.
Transposable elements are DNA sequences that are capable of changing their genome position by cut and paste or copy and paste through the enzyme transposase. This ability can be harmful for hosts if transposable elements ...
Newly evolved genes can rapidly assume control over fundamental functions during early embryonic development, report scientists from the University of Chicago. They identified a gene, found only in one specific group of midge ...
A team of University of Delaware researchers is opening wider the door for those who study the vast world of microbes. A paper published in Nature Communications on May 6 describes a new technique they developed for examining ...
The discovery that an Australian tobacco plant studied internationally as part of plant breeding programs is actually the genetic "weirdo" of its family holds huge potential for food security, experts say.
New research findings by John Innes Centre (JIC) scientists have helped to settle an important debate in the field of epigenetic inheritance.
