- The term protobionts is used describing the First formed . . . - Toppr
Protobionts were transformed into a first living prokaryotic organism with gradual improvement in metabolism, growth and reproduction Thus, the correct answer is option D
- Protocell or eobionts, the first forms of life that appeared in sea . . .
Protocells or protobionts are nucleoprotein molecules which have free-living genes They are similar to the present day virus and mycoplasma and hence, they were anaerobic They were heterotrophs which obtained their energy and nutrients from the organic molecules Hence, they were chemoheterotrophs
- Which one of the following is incorrect about the characteristic of . . .
Protobionts exhibit some of the properties associated with life, including simple reproduction, metabolism and excitability, as well as the maintenance of an internal chemical environment different from that of their surroundings It has been suggested that they are a key step in the origin of life on earth
- Which of the following is the correct sequence of events in the origin . . .
all these organic compounds were then aggregated together and surrounded by a feeble membrane this structure was known as the protobionts Much more complex DNA based genetic system evolved after that SO, the correct option is 'II, III, I, IV' Was this answer helpful?
- Which of the following is the correct sequence of events in the origin . . .
Which of the following is the correct sequence of events in the origin of life based on theory of chemical evolution? I Formation of protobionts II Synthesis of simple organic compounds III Synthesis of complex organic compounds IV Formation of nucleic acids as genetic material
- Which one of the following is incorrect aboutthe . . . - Toppr
Which one of the following is incorrect about the characteristics of protobionts (coacervates and microspheres) as envisaged in the abiogenic origin of life?
- Which is the correct sequence of events in the origin of life?
Which is the correct sequence of events in the origin of life? I Formation of protobionts II Synthesis of organic monomers III Synthesis of organic polymers IV Formation of DNA based genetic systems
- In his laboratory apparatus, Stanley Miller synthesized
Stanley Miller was an American chemist who conducted one of the most exciting experiments in modern science Miller's famous experiment gave an idea of how life could have developed out of non-living matter, a process called abiogenesis Miller's experimental interests at the University of Chicago were in the field of astrobiology, which is the study of life in the universe, including its
