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.
RNA (ribonucleic acid) molecules differ from DNA molecules in several ways. RNA molecules are single-stranded, and their nucleotides contain ribose rather than deoxyribose sugar. Like DNA, RNA nucleotides each contain one of four organic bases, but whereas adenine, cytosine, and guanine nucleotides occur in both DNA and RNA, thymine nucleotides are found only in DNA. In place of thymine nucleotides, RNA molecules contain uracil nucleotides. The first step in the delivery of information from the nucleus to the cytoplasm is the synthesis of a type of RNA called messenger RNA (mRNA). In messenger RNA synthesis, RNA nucleotides form complementary base pairs with a section of a strand of DNA that encodes a particular protein.
