Question : Plant genetic material in 'Gene-Bank' is preserved at -196°C in liquid nitrogen as
Option 1: seedling and meristem
Option 2: mature seed (dry)
Option 3: pre-mature seed (high moisture)
Option 4: ripe fruit
Correct Answer: mature seed (dry)
Solution : The correct answer is mature seed (dry) .
Gene bank is a method of conservation used to preserve mature seeds for future use. This is achieved by storing the seeds at a temperature of -196 degrees Celsius, using a cryogenic technology. By subjecting the genetic material to such ultra-low temperatures, biological activities are prevented, effectively putting the seeds in a state of suspended animation.
