Genes that are exceptionally long or short are overrepresented in some published reports, which can lead to misinterpreted results.

Only recently have scientists directly witnessed this most pivotal of events in biology, thanks to new technology that allows them to observe the process in living cells. It’s teaching them a lot.

Two studies contest the idea that the noncoding sequences are just “junk DNA,” demonstrating that they play important roles in the regulation of cell growth.

Turning to molecular genetics, the Baylor pediatric neurologist and geneticist works to discover the biological basis for the rare neurological diseases she sees in her patients.

Lampbrush chromosomes, first observed in the 19th century, still offer an unparalleled glimpse into how genetic information is organized in the cell.

Pauses may help cells fine-tune gene expression.

Researchers are just beginning to scratch the surface of how several newly recognized epigenetic changes function in the genome.

To expand the basic nucleotide alphabet, many species modify their DNA with epigenetic marks.
