59. DNA Origami in Origins of Life Research

Amelie Heuer-Jungemann (MPI Biochemistry, DE)

17.06.22, 13:30

Although clearly not prebiotically plausible, I will show that DNA origami presents an excellent model to understand how early forms of cell walls made of nucleic acids could have formed in order to achieve non-spherically shaped protocells. By making use of simple self-assembly reactions, DNA origami are able to form large assemblies and stabilizing lattice networks on lipid membranes,...

75. A modular RNA polymerase ribozyme with promoter recognition topologically associates with its template

Early in the evolution of life the replication of genomes and the transcription of functional genes would have been of vital importance. RNA catalysts or ribozymes appear likely to have played a role in such activities. In extant biology, DNA replication is initiated by binding events at an origin of replication that assemble two topologically clamped replication forks capable of sustained...

58. Some like it hot – adaptation strategies of hyperthermophilic Archaea

Dina Grohmann (U Regensburg, DE)

17.06.22, 14:20

Since Louis Pasteur, it was beyond imagination that life could thrive at temperatures above the boiling point of water as bacteria could be safely killed when incubated at 100°C. The discovery of Archaea as third domain of life did not only revolutionize the tree of life, but led to the identification of heat-loving organisms that thrive at temperatures up to 122°C. Many of these...
