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.
RNA 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.

In most cases, no, RNA is single stranded. However, some viruses have double stranded RNA.
RNA is basically unzipped DNA. It would look like a single helix with one part of each base pair sticking off the side.
RNA is singal helical structure but in some bacteria it is double helical in nature.....e.g. is bacterio phage
Double helix is 2 polynucleotide strands spun into a spiral shape. Rna stands for ribonucleic acid that controls protein synthesis and is single- stranded.
No, 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.
No, it is a single helix.
When DNA double helix after RNA polymers stops producing causes one thing. The thing it cause is a transcription bubble.
DNA is double stranded while RNA only has one strand.
When DNA and/or RNA are in the double helix configuration each helix is the complementary sequence of the other.
DNA is double helix and rna is single stranded and twisted
No, DNA, from difference with the RNA, is a double strand of nucleotides. DNA, double strand (hence the double helix nickname). RNA, single strand.
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 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.
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

DNA is double stranded while RNA only has one strand.
the difference is that DNA is a double helix and RNA is a single chain
The DNA double helix unwinds.
When DNA and/or RNA are in the double helix configuration each helix is the complementary sequence of the other.
A DNA molecule has the shape of a double-stranded helix.
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.
