Quasispecies and virus

European Biophysics Journal, 2018
Quasispecies theory has been instrumental in the understanding of RNA virus population dynamics because it considered for the first time mutation as an integral part of the replication process. The key influences of quasispecies theory on experimental virology have been: (1) to disclose the mutant spectrum nature of viral populations and to evaluate ...

Quasispecies productivity

The Science of Nature
The quasispecies theory is a helpful concept in the explanation of RNA virus evolution and behaviour, with a relevant impact on methods used to fight viral diseases. It has undergone some adaptations to integrate new empirical data, especially the non-deterministic nature of mutagenesis, and the variety of behavioural motifs in cooperation, competition,

Hepatitis C viral quasispecies

Journal of Viral Hepatitis, 1999
Analysing significant numbers of cDNA clones of the hepatitis C virus (HCV) from single isolates provides unquestionable proof that the viral genome cannot be defined by a single sequence, but rather by a population of variant sequences closely related to one another.

What Is a Quasispecies?

2006
The concept of the quasispecies as a society formed from a clone of an asexually reproducing organism is reviewed. A broad spectrum of mutants is generated that compete one with another. Eventually a steady state is formed where each mutant type is represented according to its fitness and its formation by mutation.

Theoretical Models of Generalized Quasispecies

2015
Theoretical modeling of quasispecies has progressed in several directions. In this chapter, we review the works of Emmanuel Tannenbaum, who, together with Eugene Shakhnovich at Harvard University and later with colleagues and students at Ben-Gurion University in Beersheva, implemented one of the more useful approaches, by progressively setting up ...

Quasispecies in Time-Dependent Environments

2006
In recent years, quasispecies theory in time-dependent (that is, dynamically changing) environments has made dramatic progress. Several groups have addressed questions such as how the time scale of the changes affect viral adaptation and quasispecies formation, how environmental changes affect the optimal mutation rate, or how virus and host co-evolve.

Isomorphism of Quasispecies and Percolation Models

Journal of Theoretical Biology, 2000
Population dynamics of tRNA-like macromolecules and viruses have been interpreted by Eigen (1971, Naturwissenschaften58, 465-526) on the basis of the "quasispecies" model. The present paper contains a qualitative analysis of the similarities between Eigen's quasispecies model and percolation models.
