There are two basic morphologies of bacteriophages. The virion is either isomeric, in the shape of a polyhedral, such as an icosahedral, sometimes with a tail and tail fibers, or it is helical, in a spiral filamentous formation..

Conclusions. A vector is a DNA molecule that has the abil­ity to replicate autonomously in an appropri­ate host cell and into which the gene of inter­est (a foreign genetic sequence) is integrated. When we insert a foreign genetic sequence into the vector the aim is either to obtain numer­ous copies of the gene of interest or to obtain the product of that.. A . virus.
