Is DNA and RNA double-standard?

No, DNA is usually double-stranded, consisting of two strands that are complementary to each other. RNA, on the other hand, is usually single-stranded. There are exceptions to this, such as certain viral RNA genomes that can be double-stranded.


Do chimps have single-stranded DNA?

No, chimpanzees, like all organisms, have double-stranded DNA in their cells. Double-stranded DNA consists of two strands of nucleotides that are complementary and form a double helix structure. Single-stranded DNA is rare in organisms and is usually found transiently during processes like replication or transcription.


Is influenza single strand or double strand RNA?

It is single stranded RNA. Importantly, it is also a segmented genome that allows it to have large genetic diversity.


Is RNA found in a double stranded state in the cyoplasm?

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,


What is the name of one of the single strands in a Double stranded chromosome?

It is called a chromatid.Two chromatids are hold by centromere.
