No RNA is a single-stranded chain of nucleotides. The double helix is formed by two nucleotide strands of DNA not RNA. RNA can form secondary structures, but not the double helix seen with DNA.

∙ 14y agoRNA does form a double helix. It is unlike DNA in so far as RNA will typically form an A-form helix, whereas DNA alters between A-form and B-form helices, with the B-form being more common in cells. The switch between A and B form DNA is controlled, at least in part, by humidity - something discovered by Rosalind Franklin in 1953 when she was working on solving the structure of DNA. The structure of DNA was actually solved by James Watson and Francis Crick at the Laboratory of Molecular Biology in Cambridge (UK), although they could not have done it without the work of Rosalind Franklin and Maurice Wilkins (see the Nobel Prize website1 for more info on their work).
The double helical nature of nucleic acids is due to hydrogen bonding between the bases, which are identical in DNA and RNA (with the exception of 1: DNA contains thymidine; RNA contains uracil in its place). This means that DNA-DNA double helices, DNA-RNA double helices and RNA-RNA double helices can be formed.

∙ 11y agoIn most cases, no, RNA is single stranded. However, some viruses have double stranded RNA.

∙ 13y agoRNA is basically unzipped DNA. It would look like a single helix with one part of each base pair sticking off the side.

∙ 13y agoRNA is singal helical structure but in some bacteria it is double helical in nature.....e.g. is bacterio phage
Wiki User
∙ 13y agoDouble helix is 2 polynucleotide strands spun into a spiral shape. Rna stands for ribonucleic acid that controls protein synthesis and is single- stranded.
Wiki User
∙ 8y agoNo, RNA is not normally a double helix, but very short complementary sections of an RNA molecule sometimes form "hairpin double helix" sections along the length of the molecule.

What happens to the DNA double helix after RNA polymerses have stopped producing its RNA transcripts?
When DNA double helix after RNA polymers stops producing causes one thing. The thing it cause is a transcription bubble.
What is major difference between normal DNA helix and RNA helix?
DNA is double stranded while RNA only has one strand.
What is complementary sequence?
When DNA and/or RNA are in the double helix configuration each helix is the complementary sequence of the other.
How are DNA and rna molecule oriented and structed in the nitrogenous bases?
DNA is double helix and rna is single stranded and twisted
Is DNA a single strand of nucleotides?
No, DNA, from difference with the RNA, is a double strand of nucleotides. DNA, double strand (hence the double helix nickname). RNA, single strand.
What is a double helix DNA or RNA?
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.
What is the major difference between normal DNA double helix and RNA double helix?
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.
What is a component of RNA?
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
What happens to the DNA double helix after RNA polymerses have stopped producing its RNA transcripts?
When DNA double helix after RNA polymers stops producing causes one thing. The thing it cause is a transcription bubble.
What is major difference between normal DNA helix and RNA helix?
DNA is double stranded while RNA only has one strand.
Difference between the DNA and RNA?
the difference is that DNA is a double helix and RNA is a single chain
What happens right before RNA polymerase begins work?
The DNA double helix unwinds.
What is complementary sequence?
When DNA and/or RNA are in the double helix configuration each helix is the complementary sequence of the other.
What is a single helix molecule?
A DNA molecule has the shape of a double-stranded helix.
How does the double helix structure of RNA resemble the structure of DNA?
First of all, RNA is a single helix. It isn't really similar to the DNA in the obvious shape. In DNA there two long polynucleotides chins which are right handed double helix. the chains are antiparallel to each other. while in RNA there is only a single chain.
How are DNA and rna molecule oriented and structed in the nitrogenous bases?
DNA is double helix and rna is single stranded and twisted
In what shape does DNA acid exist?
double helix
