The term double helix refers to the structure formed by double-stranded molecules of nucleic acids. Only DNA forms a double helix because RNA is only single-stranded.
Because DNA forms a double helix.
Both DNA and RNA can exist in the double helix form, but only DNA is completely stable as a double helix. The double helix RNA is usually only short "hairpin" sections folding back on itself, never the long essentially linear form of double helix DNA.
The sugar ribose is unique to RNA, as well as the nitrogenous Uracil. Also, RNA has a single helix structure in comparison to the double helix of DNA
Rna
It typically forms a single sometimes twisted strand, not a double helix like DNA.
It typically forms a single sometimes twisted strand, not a double helix like DNA.
DNA is double stranded while RNA only has one strand.
DNA
When DNA double helix after RNA polymers stops producing causes one thing. The thing it cause is a transcription bubble.
the difference is that DNA is a double helix and RNA is a single chain
When DNA and/or RNA are in the double helix configuration each helix is the complementary sequence of the other.
