Once the virus has successfully gained entry into the host cell, the endosome acidifies, which alters virus topology by causing capsid components to disassociate.

Once the early genes have liberated adequate virus proteins, replication machinery, and replication substrates, replication of the adenovirus genome can occur.

Once the viral components have successfully been replicated, the virus is assembled into its protein shells and released from the cell as a result of virally induced cell lysis.

Once the virus is inside the host cell, the capsid dissolves, and the RNA gets replicated, and translated into viral proteins by the cell's ribosomes using a cap-independent mechanism driven by the internal ribosome entry site element.

Once a person becomes infected with CMV, the virus stays in his / her body fluids throughout his or her lifetime.

Once this has happened, the contents of the virus, including its RNA genome, are free to pour out into the cell's cytoplasm.

Once inside, an eclipse phase begins, in which the virus disappears and all appears normal within the cell.

Once recruited, he goes undercover as a scholar winning a prize to explore suspicious rumors of some sort of virus at Herod Sayle's manufacturing plant in Cornwall.

Once integrated into the host cell ’ s genome, the virus can lay dormant in the asymptotic stage for extended periods of time without being detected by the immune system or can cause lysis of the cell.

Once the virus was introduced to Warlock's unique physiology, it mutated and became even more contagious.

Once in the cytoplasm, the intact virus is translocated to the nucleus prior to uncoating.

Once he has received this blessing, the abbot not only becomes father of his monks in a spiritual sense, but their major superior under canon law, and has the additional authority to confer the ministries of acolyte and lector ( formerly, he could confer the minor orders, which are not sacraments, that these ministries have replaced ).

Once a node has been found in a balanced tree, the next or previous nodes can be explored in amortized constant time.

Once it has come to rest, the jack is aligned to the centre of the rink and the players take turns to roll their bowls from the mat towards the jack and thereby build up the " head ".

Once the first bowl has taken place, the other side has the opportunity to bowl.

Once a beaver has sounded the alarm, nearby beavers will dive and may not reemerge for some time.

Once the expander has reached an acceptable size, it may be removed and replaced with a more permanent implant.

Once one copy of a document has been produced, printing further copies is often quicker by means of a device called a " thermoform ", which produces copies on soft plastic.

Once published by BSI a PAS has all the functionality of a British Standard for the purposes of creating schemes such as management systems and product benchmarks as well as codes of practice.

Once a prototype has passed the tests at a certification lab, and that model is being constructed under the control of a certified quality system, the device is entitled to bear a CE mark, indicating that the device is believed to be safe and reliable when used as directed.

Once an idea has been reduced to tangible form, for example by securing it in a fixed medium ( such as a drawing, sheet music, photograph, a videotape, or a computer file ), the copyright holder is entitled to enforce his or her exclusive rights.

Once the term of a copyright has expired, the formerly copyrighted work enters the public domain and may be freely used or exploited by anyone.

Once the software has loaded, the computer is able to execute the software.

Once this islands were covered with savanna on the plains and arid shrubland on the mountainsides, but over 500 years of human habtitation, since colonisation by the Portuguese in the 15th century, nearly all the original vegetation has been cleared by widespread agriculture including the grazing of goats, sheep and cattle and the planting of imported crop species.

Once labelled by Rolling Stone as " the most controversial woman in the history of rock ", Love's sometimes outrageous behavior has given her a lasting place in pop culture, as well as a polarizing reputation in the media.
