The genetic insert for PanAd3 and MVA viral vectors is the same codon-optimised single synthetic DNA fragment encoding the RSV proteins F (fusion protein, F0ΔTM), N (nucleocapsid protein) and M2 1 (matrix protein), shown schematically in figure 1. Deletion of the E1 and E4 loci of PanAd3 renders the adenovirus replication defective, and MVA cannot naturally replicate in mammalian cells.
Using a technique called error-prone PCR, which is a faulty version of the way cells naturally replicate their genes, they generated a large collection of different mutated forms of the gene.
But because RNA itself doesn't naturally replicate, cells subject to REPAIR's RNA fixes don't pass on changes to the next generation of cells, and engineered genes can revert to their original form.
It's like a naturally replicating human-made virus.
Second, it removes the focus of the experiment, at least in the mind of the participant, away from the visuomotor distortion, more naturally replicating the scenarios in which visuomotor transformation is required.
Studying how population differentiation occurs in M. emersoni along several naturally replicated ecological gradients on five Sky Islands in Arizona provides a unique opportunity to ask whether organismal development facilitates repeatable, and thus, predictable responses to similar ecological and climate changes on each Sky Island.
Because cotton domestication involved in two different allopolyploid species in the New World as well as two different diploid species in the Old World [ 32, 36], a naturally replicated "experiment" of domestication provides the opportunity to evaluate potential parallelisms in ROS-related responses across ploidy levels and continents.
Mr. Bowman also argued in briefs that soybeans naturally "self-replicate or 'sprout' unless stored in a controlled manner," meaning that "it was the planted soybean, not Bowman," that created the new seeds.
Solutions to the continuing problems of improved composite technologies may lie in replicating naturally occurring systems.
The two viruses replicate naturally in the animal's liver, which suggests that their lifecycle is similar to human hepatitis C virus.
