EVERYDAY SCIENCE

Detailed explanation-1: -They are called DNA viruses if they contain DNA in their genome and called RNA viruses if they contain RNA as genetic material. Nucleic acid is also present in the bacteria in the form of a nucleoid. Thus, bacteria and viruses both contain nucleic acids in their genetic material. Therefore, the given option is true.

Detailed explanation-2: -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-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: -Viruses contain either RNA or DNA as their genetic material. DNA in most organisms is a double-stranded structure, based on Watson and Crick pairing; however, in viruses, DNA and RNA can be either single-stranded or double-stranded.

Detailed explanation-5: –bacteria have double stranded genetic material whereas viruses have single or double stranded genetic material. In a person with TB, the dormant bacteria may be activated after several years. The bacteria multiply rapidly, resulting in severe lung damage. The bacteria are released from the tubercles.
