Detailed explanation-1: -Genetic material-Both bacteria and viruses have genetic material (nucleic acid). In bacterial cells, the genetic material is contained in a chromosome which is a strand of DNA. While they do not have a nucleus, the genetic material of these organisms is contained in a region generally known as the nucleoid.
Detailed explanation-2: -Both bacteria and viruses reproduce by making identical copies of themselves, and the instructions for doing this are stored in their DNA.
Detailed explanation-3: -Bacterial and viral infections have many things in common. Both types of infections are caused by microbes (bacteria and viruses) and are spread by things such as coughing and sneezing, contact with infected people, surfaces, food, water, pets, livestock, or insects such as fleas and ticks.
Detailed explanation-4: -A virus is an infectious microbe consisting of a segment of nucleic acid (either DNA or RNA) surrounded by a protein coat. A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself.
