<prompt> Bacteria aquires restriction endonuclease by horizontal transfer. The result would be -Bacteria can undergo mutationBacteria causes death of host DNABacteria cannot survive because it lacks DNA methylase that protects the host DNAIt helps in DNA proof reading in bacteria  <response>: Any bacteria is protected against its own RE by a companion enzyme, site-specific DNA methylase, which methylates the restriction sites recognised by that particular RE. If any bacteria acquire new RE by horizontal transfer, this RE will cleave bacterial DNA and kill bacteria.
