Question

Oparin’s theory is based on which of the following options?
a. Artificial synthesis
b. Spontaneous generation
c. God’s will
d. All of the above

Answer 1

Hint: It is a theory about the origin of life on Earth in which it is assumed that life originated from inorganic matter with different chemical processes under specific conditions which was available only on primitive Earth.

Complete answer:
If we talk about life on Earth. It is still a puzzle about how actually life evolved on Earth. How all organisms came into existence. Thus, to solve this problem different scientists gave their theories about the origin of life and primitive conditions on this beautiful Earth.

Oparin’s theory is one among the theories which is proposed for the origin of life. According to this theory, the origin of life is a physicochemical change in which under specific conditions, atoms react and become molecules and molecules react to each other to become inorganic and organic compounds.

Thus, we can say that life originates from pre-existing nom-living matter which undergoes various changes due to environmental changes and conditions which occur spontaneously. In this process, firstly inorganic matter was formed from environmental changes on Earth.
Then organic matter starts forming due to further environmental changes on Earth. Then macromolecules required for life to exist, started forming. So, Firstly RNA molecules started accumulating inside lipid bilayer molecules.

But as RNA is unstable macro-molecule thus it evolved to DNA and hence DNA came into existence. And transcription and translation of genetic material started. This is how, according to this theory, life on Earth originated.

So, after discussing all theories we can say that this theory Is based on “artificial synthesis”.
Hence, the correct answer is option (A).

Note: Artificial synthesis is the process in which some products or results are obtained from the naturally existing materials and not produced naturally. This method is used for preparation of many products like artificial genes, artificial organs, etc.
