single stranded RNA
It depends what you mean by double stranded. If you mean two separate RNA strands, perfectly complementary to one another and existing as a basepaired structure in the cytoplasm, then no. Double stranded RNA like that only occurs in some types of viruses (and cells infected by them... so I guess the cytoplasm of a cell infected by a double stranded virus might have a lot of this kind of double stranded RNA). However, if you mean double stranded in the sense of a single RNA molecule folding back on itself and basepairing with itself - forming stem loops and more complicated structures - that kind of RNA double-strandedness is extremely common. All tRNA's and rRNA's for example exhibit this kind of double-strandedness. Nucleic acids are unstable in single stranded states and will spontaneously fold back on themselves if there is no other strand to basepair with. Nucleic acids are inherently unstable in a single stranded state. Thus,
If all the bands on an electrophoresis gel are the same color, it indicates that the single stranded DNA sample consisted of one kind of nucleotide sequence. This could be due to the sample being homogeneous, with all DNA molecules having the same sequence, resulting in identical bands on the gel.
Transcripts are molecules of RNA that are produced during the process of transcription, which is the first step in gene expression. These molecules carry the genetic information transcribed from DNA and are then used to guide the synthesis of proteins in the cell.
If you're stuck somewhere with no way of getting anywhere else, you're stranded. If you run out of gas while driving in the desert, you'll be stranded until someone finds you. Good luck! If you're stranded, you probably experienced some kind of transportation failure.
single stranded RNA
The mRNA molecule encodes the protein product in the cell for translation. It is a double stranded, base-paired, ribonucleic acid that typically encodes a single gene, or protein, product.

DNA and RNA are the two kinds of nucleic acids. DNA is a double-stranded "hard-copy" information molecule, and is irreplaceable. RNA is a temporary "soft-copy" information molecule and is single stranded.
The HIV virus contains two copies of single-stranded RNA.
If all the bands on an electrophoresis gel are the same color, it indicates that the single stranded DNA sample consisted of one kind of nucleotide sequence. This could be due to the sample being homogeneous, with all DNA molecules having the same sequence, resulting in identical bands on the gel.
DNA is typically double-stranded, comprising two long chains of nucleotides that are twisted around each other to form a double helix structure. Each strand is made up of a sequence of nucleotides (adenine, thymine, cytosine, and guanine) linked by hydrogen bonds.
I recommend that you obtain, read, and understand books about the area(s) in which you may become stranded BEFORE you go there. That is known as advanced planning.
Detergents doesn't contain proteins.

Round
Proteins have several roles in the body - build and repair the body - they are made into enzymes and hormones for normal body functions - they are part of the immune system -- part of antibodies, - they help with fluid balance - and a few other roles. Proteins do not insulate vital organs. A special kind of fat helps to insulate and protect vital organs.
