why is rna less stable
Report Abuse. Yes, becasue it is double stranded it is a closed system with no areas for molecular bonding. RNA, being an single-stranded open system, is more prone to chemical reactions (which is some cases is a good thing) but therefore it is less stable.eport Abuse. Because RNA has a hydroxyl group at the 2' position on the ribose backbone. This is an easy site for degradation to occur. DNA does not have this site (it is replaced by a hydrogen), that is why its backbone is called deoxyribose.
