People who have Ehlers-Danlos syndrome, vascular type, often share distinctive facial features of a thin nose, thin upper lip, small earlobes and prominent eyes. They also have thin, translucent skin that bruises very easily.
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.
The absence of one Oxygen is the key for extending DNA's longevity. When the 2' Oxygen is absent in deoxyribose, the sugar molecule is less likely to get involved in chemical reactions(the aggressive nature of Oxygen in chemical reactions are famous). So by removing the Oxygen from deoxyribose molecule, DNA avoids being broken down. In an RNA's point of view the Oxygen is helpful, unlike DNA, RNA is a short-term tool used by the cell to send messages and manufacture proteins as a part of gene expression.
