In animals with large genomes, finding cis-regulatory elements can be very challenging. Enhancers can be located tens/hundreds of kb away from their target promoters. We face this challenge in Parhyale, with >3 Gbp genome.
We just published a preprint describing how we are tackling this problem. /1

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?

Excited to share our latest work in @science.org on a new small polymerase.

Confocal microscopy image of a juvenile sea star (Patiria miniata) viewed from the oral side. The animal has a five-armed, star-shaped body with a central nerve ring. The nervous system is labeled in green, forming radial nerve cords extending into each arm, and cell nuclei are labeled in red throughout the animal. The image appears against a black background and has a holiday-ornament-like appearance.

Felt a little festive at the microscope this morning for #FluorescenceFriday 🎄

Here’s the nervous system of a juvenile sea star ⭐️

Green = acetylated tubulin, red = nuclei

Happy holidays!
