Endogenous retroviruses are always in the state of a provirus.

We only now have the opportunity to understand the many roles these endogenous retroviruses may play."

Endogenous retroviruses can play an active role in shaping genomes.

Some sequences may have no biological function for the organism, such as endogenous retroviruses.

A certain type of latency could be ascribed to the endogenous retroviruses.

Much of the current debate focuses on viruses that pigs inherit, called porcine endogenous retroviruses.

As much as one third of the human genome, our complete genetic record, was made up of these so-called endogenous retroviruses.

Endogenous retroviruses express, carry a signal, coordinate the activation of specific elements in the genetic memory storage.

It is thought that proviruses may account for approximately 8% of the human genome in the form of inherited endogenous retroviruses.

"The latest estimate is that as much of one third of our genome could consist of endogenous retroviruses.

The reasons why chickens are so receptive to such transmission may involve unusual characteristics of stability or instability as they relate to endogenous retroviruses.

Endogenous retroviruses are remnants of ancient viral infections, found in the genomes of most, if not all, mammalian species.

These endogenous retroviruses (ERVs), contrasted with exogenous ones, now make up 5-8% of the human genome.

In vertebrates EVEs derived from retroviruses (endogenous retroviruses) are relatively common.

A special variant of retroviruses are endogenous retroviruses which are integrated into the genome of the host and inherited across generations.

They are called endogenous retroviruses, because once they infect the DNA of a species they become part of that species.

Coffin is one of the country's most distinguished molecular biologists, and was one of the first to explore the role of endogenous retroviruses in human evolution.

Remarkably, the capture of syncytin or syncytin-like genes has occurred independently, from different groups of endogenous retroviruses, in diverse mammalian lineages.

Endogenous retroviruses are not formally included in this classification system, and are broadly classified into three classes, on the basis of relatedness to exogenous genera:

Endogenous retroviruses (or ERVs) are remnant sequences in the genome left from ancient viral infections in an organism.

Many endogenous retroviruses, closely related to exogenous gammaretroviruses, are present in the DNA of mammals (including humans), birds, reptiles and amphibians.

Endogenous retroviruses and other EVEs that occur as proviruses can potentially remain capable of producing infectious virus in their endogenous state.

During pregnancy in viviparous mammals, endogenous retroviruses (ERVs) are activated and produced in high quantities during the implantation of the embryo.

Different strains of mice may have different numbers of endogenous retroviruses, and new viruses may arise as the result of recombination of endogenous sequences.

Endogenous retroviruses are endogenous viral elements that are derived from retroviruses, and are abundant in the genomes of jawed vertebrates.
