Graph‐Based Analysis of RNA Secondary Structure Similarity Comparison

open access: yesComplexity, Volume 2021, Issue 1, 2021., 2021
In organisms, ribonucleic acid (RNA) plays an essential role. Its function is being discovered more and more. Due to the conserved nature of RNA sequences, its function mainly depends on the RNA secondary structure. The discovery of an approximate relationship between two RNA secondary structures helps to understand their functional relationship better.
