Vedclass · Answer

(D) According to the Oparin-Haldane hypothesis of chemical evolution, the sequence of appearance of substances on primitive Earth was as follows:$1$. Simple inorganic molecules like $NH_3$ (ammonia), $H_2O$, and $CH_4$ were present.$2$. These reacted to form simple organic molecules like amino acids.$3$. Simple organic molecules polymerized to form complex organic molecules like proteins.$4$. Further complexity led to the formation of nucleic acids ($RNA$/$DNA$) which were essential for self-replication.Therefore, the correct sequence is $Ammonia \rightarrow Amino \ acids \rightarrow Proteins \rightarrow Nucleic \ acids$.

In the context of the origin of life, in what sequence did the substances appear on Earth?
