Deadly virus turns honey bees into Trojan horses

Some parvoviruses encapsidate (enclose) both plus and minus strands of DNA, but in separate virions; others encapsidate only the minus strand. In each cases, the ssDNA is copied contained in the cell into dsDNA, which is then itself copied into mRNA.

The 2014 outbreak of Ebolain West Africa, and the 2009 H1N1/swine flu pandemic (a widespread global outbreak) probably come to thoughts. Recombinant viruses can be used as vectors to carry (transduce) chosen genes into cells. In this strategy, viral genes required for the lytic cycle are replaced by other genes.

Every day you breathe in over one hundred,000,000 viruses.Antibodies assist your immune system battle again.

The use of viral vectors for gene remedy is still in its infancy, but has nice potential for therapy of various diseases. During lytic replication, host-cell ribosomes and enzymes are used to specific viral proteins, which then replicate the viral genome and bundle it …
