NURSING ANM AND GNM

Detailed explanation-1: -Size. Bacteria are giants when compared to viruses. The smallest bacteria are about 0.4 micron (one millionth of a meter) in diameter while viruses range in size from 0.02 to 0.25 micron. This makes most viruses submicroscopic, unable to be seen in an ordinary light microscope.

Detailed explanation-2: -Viruses are pathogenic because they need to hijack the cellular machinery of living cells to multiply. Viruses are smaller than bacteria. The size of a typical virus is 20 to 200 nm (diameter). By looking at the size of typical bacteria and viruses, it can be said that viruses are smaller than bacteria.

Detailed explanation-3: -Viruses are usually much smaller than bacteria with the vast majority being submicroscopic, generally ranging in size from 5 to 300 nanometers (nm). Helical viruses consist of nucleic acid surrounded by a hollow protein cylinder or capsid and possessing a helical structure.

Detailed explanation-4: -Viruses are much smaller. The largest of them are smaller than the smallest bacteria. Unlike bacteria, viruses can’t survive without a host. They can only reproduce by attaching themselves to cells.

Detailed explanation-5: -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.
