Detailed explanation-1: -Viruses are smaller and simpler in construction than unicellular microorganisms, and they contain only one type of nucleic acid-either DNA or RNA-never both.
Detailed explanation-2: -Unlike cells (e.g. bacteria, plant and animal cells), viruses contain either DNA or RNA, never both; the viral nucleic acid is either single or double stranded. Viruses with a DNA core are capable of surviving in the nucleus of the cell they infect, using the host’s biochemical machinery to replicate their DNA.
Detailed explanation-3: -Viruses contain nucleic acid as RNA or DNA. These molecules possess all the genetic information of the virus.
Detailed explanation-4: -Final Answer: Viruses do not infect bacteria, fungi and algae is not the correct statement.
