All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

A research team has unveiled a breakthrough in understanding how specific genetic sequences, known as pseudogenes, evolve. Rice University's Peter Wolynes and his research team have unveiled a ...

A new international study suggests that ancient viral DNA embedded in our genome, which were long dismissed as genetic "junk," may actually play powerful roles in regulating gene expression. Focusing ...

DNA is often compared to a written language. The metaphor leaps out: Like letters of the alphabet, molecules (the nucleotide bases A, T, C and G, for adenine, thymine, cytosine and guanine) are ...

The human genome is chock full of what scientists once considered "junk DNA." This DNA is actually something called transposable elements, or TEs. These are repetitive sequences found in the genome ...
