Summary Introduction
To determine:
That how the definition of life need to be altered to allow viruses and prions to qualify as living forms or alive.
Introduction:
Life differentiates a living being from the nonliving things on the basis of some characteristics. Organisms that could reproduce, grow, multiply or sense along with could collectively evolve and could acquire energy are considered as living forms. All living forms comprise all these characteristics.
