Question

Which culture system is used to obtain cells in the exponential phase?

(a) Single

(b) Monochronous

(c) Continuous

(d) Batch

This question was posed to me in an internship interview.

This is a very interesting question from Biotechnology in division Biotechnology Principles and Processes of Biology – Class 12

Answer 1

The correct option is (c) Continuous

To explain: The continuous culture system is used to obtain the cells in the exponential phase. In continuous culture, the fresh media is added from one side while the used media is simultaneously drained from the other side. This helps to obtain cells in a single phase.
