Nucleic acids {bacteriophage}| can act like viruses in bacterial cells. It is DNA or RNA that has protein coat. It tries to enter cell from outside and then integrate into chromosome. Bacteriophages replicate in cell along with chromosome.
Viruses {RNA virus} can have RNA instead of DNA. RNA viruses can use RNA-directed RNA polymerase for direct RNA replication. RNA viruses can use RNA-directed DNA polymerase to make DNA from RNA and then make viral RNA from DNA. RNA viruses include polio, colds, foot-in-mouth disease, rabies, cancer retrovirus, and human immune deficiency virus.
Viruses {Sendai virus} can alter membranes and allow two cells to fuse, even if they are from different species.
