Detailed explanation-1: -Like proteins, RNA structure can be described in terms of its primary (sequence), secondary (hairpins, bulges and internal loops), tertiary (A-minor motif, 3-way junction, pseudoknot, etc.) and quaternary structure (supermolecular organisation).
Detailed explanation-2: -RNA in minimum amount in a cell is mRNA.
Detailed explanation-3: -An RNA hairpin is an essential secondary structure of RNA. It can guide RNA folding, determine interactions in a ribozyme, protect messenger RNA (mRNA) from degradation, serve as a recognition motif for RNA binding proteins or act as a substrate for enzymatic reactions.
Detailed explanation-4: -Transfer RNA (tRNA) tRNA is the smallest of the 3 types of RNA, possessing around 75-95 nucleotides. tRNAs are an essential component of translation, where their main function is the transfer of amino acids during protein synthesis.
