tRNA-precursors were smaller than the modern tRNA and their primary function was to participate in the formation of new structures by joining two or more RNA molecules.
The adaptor hypothesis is the explanation of how information could be extracted from a nucleic acid into a string of amino acids in a specific sequence. The proposed explanation involved recognition between the adaptor (today tRNA) and the template nucleic acid .
Answer AND Explanation:
When sodium atoms bond with one oxygen atom they form a covalent bond. However, there has to be two sodium atoms each with an extra electron that are donated to oxygen. Each of these sodium atoms gives oxygen one electron, allowing the oxygen atom to have a full shell with eight electrons. The sodium atom loses one orbital level since the electrons are donated.
4Na + O2 → 2Na2O
