Lincoln synthesized in the laboratory a large population of variants of the RNA ...
... Gunsch said, adding that she believes it would theoretically be possible to create a living, or self-replicating system, which would not require replacement.
The researchers are currently conducting ...
Artificial system shows how a molecular soup could be exploited by a single self-replicating complex.
... of tissue. Since no other type of cell within the tissue displayed the same self-replicating tendency, the scientists concluded that the endothelial cells were the source of the tumors' growth.

... uses computer models to simulate combinations of reactions, involving membrane forming reactions, self-replicating nucleic acids and metabolic energy-producing reactions. Then it examines how these ...
... both new stem cells (called self-renewal) as well as specialized cell types ... characteristics in common with normal stem cells in that they are self-replicating and capable of giving rise to populations ...
An evolving, self-replicating RNA system adds weight to ‘RNA World’ theory of life’s emergence on earth
... accomplished biologically, using molecules instead of electrons as the basis of the logical circuitry. Self-replicating RNAs that are triggered by target chemicals could provide the functional basis ...

"These are transient, non-coding molecules that do not incorporate into the genome, but promote self-replication and have the potential to induce pluripotency," Blelloch says. "They do their thing ...
... Kellogg School of Science and Technology, choose RNA molecules because they evolve rapidly and self-replicating RNA molecules are hypothesized to be the first organic “life forms” on earth. With a ...
