Cell Fate: Another Hurdle for Evolution
When a stem cell divides, one daughter cell must maintain its stemness while the other specializes. Therein lies another truckload of requirements.
DNA Packing: One of the Supreme Wonders of Nature
The cell packs two meters of DNA into a 10-micron nucleus. How? The machinery is as intelligently designed as the genome itself.
Cells Use Loop Extrusion to Keep DNA Optimized
A paper illustrates the action of DNA loop extrusion processes, which serve multiple functions to maintain the genome, with an interesting graphic: gears.
Histone Code: A Challenge to Evolution, an Inference to Design
Histones are responsible for organizing and packaging the DNA of a cell nucleus into structural units known as nucleosomes.
Adam and the Genome and “Nonfunctional” Pseudogenes
Venema cites the vitellogenin pseudogene as supposedly demonstrating common ancestry between humans and birds, such as chickens.
