Is a group best off if everyone co-operates ? Theory often considers this to be so ( e . g . the “conspiracy of doves” ) , this understanding underpinning social and economic policy .

However , we discovered in a laboratory experiment involving yeasts that a population can grow more and faster when there is a mix of “cheats” and “co-operators . ” In this case “co-operator” cells produce a protein ( invertase ) that breaks d... | [

The mechanistic details underlying the assembly of rod-shaped chromosomes during mitosis and how they segregate from each other to act as individually mobile units remain largely unknown .

Biotrophic eukaryotic plant pathogens require a living host for their growth and form an intimate haustorial interface with parasitized cells .
