Question

Quizplus · Accepted Answer

A pure culture is a population of identical cells, meaning they are all genetically identical and have the same properties. This is typically achieved through techniques such as streak-plating, in which individual cells are separated and grown into colonies of identical cells. Such a culture is not necessarily certified (B), nor does it necessarily require a specific chemical medium (D), although it may be grown using a defined or undefined medium depending on the needs of the organism. It is often desirable for a pure culture to be sterile (C) to avoid contamination from other microorganisms.
