Question

A scientist shines ultraviolet light on a colony of blue colored bacteria. She then places colonies of the bacteria in separate Petri dishes. After allowing the bacteria to replicate for several generations, the scientist observes that some of the dishes now contain colonies with purple and red colored bacteria. What can be concluded from this observation?

Answer 1

Hi there,

The UV light can affect the colony of blue bacterium allowing it to replicate for several generations. The UV light causes Mutation in bacteria. The mutagen present in the UV light causes mutation in Bacteria. As we know that Mutation is a change in the genetic material and can impart more functionalities in an organism.

Hope it helped.
