Which one of the following is incorrect about the characteristics of protobionts (coacervates and microspheres) as envisaged in the abiogenic origin of life?
A
They were partially isolated from the surroundings.
B
They could maintain an internal environment
C
They were able to reproduce.
D
They could separate combinations of molecules from the surroundings.
(AIPMT-2008)
Solution
(c) : The condition for origin of life, partial isolation, has been attained within aggregates of artificially formed prebiotic molecules. These aggregates are called protobionts which can separate combinations of molecules from the surroundings. They maintain an internal environment but are unable to reproduce. Two important protobionts are coacervates and microspheres.
