How plastid genetic information survived (or didn’t) the endosymbiotic experience
Check out other memorable images and videos that were submitted to this year’s Labby Multimedia Awards.
Telomeres are repetitive, noncoding sequences that cap the ends of linear chromosomes. They consist of hexameric nucleotide sequences (TTAGGG in humans) repeated hundreds to thousands of times. Telomeres protect the protein-coding sequences of DNA on
A transition-state mimic has the power to bind an enzyme at its tipping point as strongly as any available inhibitor and more strongly than most, preventing enzymatic activity. In order to replicate the structure of an enzyme’s transition state, whic
Vitamin D has a variety of actions in the body. It binds to the vitamin D receptor (VDR), which then binds to the retinoid X receptor (RXR) and activates the expression of numerous genes. Through this mechanism, vitamin D promotes calcium absorption
Genomicist Mark Stoeckle and three high school students have taken do-it-yourself science to a new level. Research headquarters are Stoeckle’s Upper West Side apartment, where he’s laid out pipettes, a thermocycler, and a gel reader in the spots usua
Near the turn of the millennium, James Collins and Stanislas Leibler independently undertook rather similar projects: design what would become synthetic biology’s seminal genetic circuits. And they came up with strikingly similar action plans—use E.
In fewer than 15 years, nanomedicine has gone from fantasy to reality.
Isolating specific cell types from a mass of plant or animal tissue is laborious and tricky. To study epigenetic changes and genes that are expressed differently in different cell lineages—such as cancer cells versus normal cells, or the two types of
