(25) For strands of RNA to perform even this limited replicase (self-replication) function, however, they must, like proteins, have very specific arrangements of constituent building blocks (nucleotides, in the RNA case).
Meckler, it turns out, is intimately familiar with this kind of self-replication: For years, he was a top distributor for Herbalife, a company with a long history of runins with state and federal regulators that has been accused of preying on consumers with promises of easy money and health miracles via nutritional supplements.
Chapters cover topics including: basic definitions, modeling biological systems, cellular automata metrics, searching for self-replicating systems, language structures in cellular automata, a genetic approach to the study of self-replication, and from rhythm to sound and music.
While the experiments suggest the reactions necessary for life can proceed in ice, "we are some distance from self-replication," cautions Holliger.
DNA: A nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA.
A longtime campaigner to protect seed diversity, Mooney has led ETC to call for a moratorium on all research involving molecular self-assembly and self-replication. "There is a critical need to evaluate the social implications of all nanotechnologies," the group says.
This special property for accurate self-replication allows DNA to duplicate the genes of an organism during the nuclear divisions for growth and the production of germ cells for the next generation.
A meme is a social, cultural, intellectual, or even religious unit of ideas that resembles the gene in the processes of self-replication, natural selection and evolution it undergoes.
His research interests include: nanomedicine, medical nanorobotics design, molecular machine systems, diamondoid mechanosynthesis (theory and experimental pathways), molecular assemblers and nanofactories, and self-replication in machine and factory systems.
Unlike infectious malicious programs such as viruses, such Trojan horse codes do not propagate by self-replication but instead rely on the exploitation of an end-user.
(9) According to the RNA World Hypothesis, the first living system was a polymer(s) of catalytic RNA capable of self-replication that subsequently evolved the ability to encode more versatile peptide catalysts.
So far, however, Hyde's efforts at self-replication, which Gauld has headed, have been rocky.
