Which one of the following is incorrect about the characteristics of protobionts (coacervates and microspheres) as envisaged in the abiogenic origin of life?

1. They were able to reproduce

2. They could separate combinations of molecules from the surroundings

3. They were partially isolated from the surroundings

4. They could maintain an internal environment

The first organisms were 

1. chemoautotrophs

2. chemoheterotrophs

3. autotrophs

4. eukaryotes

Identify the correct statement:

1. As the coacervates do not have lipid outer membranes and cannot reproduce, they alone could not have been the precursors of life.

2. The microspheres could not be induced to constrict but had no large amount of diversity

3. The earliest life was probably not driven by the solar energy as is seen today

4. Protobionts cannot separate combination of molecules from the surroundings or maintain an internal environment but are able to reproduce.

Which of these are considered most essential in the origin of life?

1. Enzymes

2. Nucleic acids

3. Carbohydrates

4. Proteins

Basis of life are 

(1) nucleic acids

(2) proteins

(3) nucleoproteins

(4) amino acids
