Question

Describe how the ‘OrthoRep’ experimental system allows one sequence to evolve rapidly while the essential genome evolves orders of magnitude more slowly.

Answer 1

Ans: Recently develop technique orthogonal DNA replication (OrthoRep) system is able of driving the rapid andand continuous evolution of gene in Vivo. The orthoRep uses special transcription system, the components of which (example promoter) have previous limited the strength, which orthoRep encoded gene can be expressed.

OrthoRep expression part garnt the orthoRep-encodedgenes, to span expression, matching level thoes of endigeendo sacchromyces cerevisiae genes. Specifically start that various promoter mutation as well as genetical-encoded poly (A) tail. Further shown expression level could gain using multiple gene and orthoRep system of distinct mutation rate.
