In which of the following patterns of viral replication, viruses enter a cell, replicate and then cause the cell to burst, releasing new viruses?

This method of finding a gene is used when researchers know very little about the gene they are trying to find. This process results in a complete gene library: a collection of copies of DNA fragments that represent the entire genome of an organism.

A charge, whether stationary or in motion produces a magnetic field around it. Moving charges produce only electric field in the surrounding space.

A compound with delocalised electrons is more stable than that compound would be if all its electrons were localised. The extra stability, a compound gains as a result of having delocalised electrons, is called delocalisation energy.
