What are the two strands of a double stranded chromosome called?
The double helix.
What is the indiviual strands of a double-stranded chromosome joined together by?
Chromatid
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.
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,
When do chromosome form?
The DNA-protein complex, called chromatin usually folds into characteristic formations called chromosomes. Each chromosome contains a single double stranded piece of DNA. Chromosomes are clearly seen during nuclear division.
What are the two strands of a double stranded chromosome called?
The double helix.
What is the indiviual strands of a double-stranded chromosome joined together by?
Chromatid
What does the cemtromere do?
the centromere in a double stranded chromosome is the glue like substance that holds the two strands of chromatin together( when there is only 1 chromosome it is chromatin)
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.
Is DNA double or single strand?
DNA is double stranded. It is described as a double helix, kind of like a twisted ladder.
Is trna double stranded or single stranded?
tRNA, or transfer RNA, is a single stranded molecule. The only double stranded RNA is dsRNA, or double stranded RNA. They are typically found in viruses.
What is dsDNA?
ssDNA stands for single stranded DNA and dsDNA stands for double stranded DNA. ssDNA stands for single stranded DNA and dsDNA stands for double stranded DNA.

When during mitosis do chromosomes attach to spindle fibers?
During mitosis a double-stranded chromosome attaches to a spindle fiber centromere.
When does the chromosome number double?
The chromosome number only doubles when two haploid gametes form to produce a diploid zygote. Example: In humans, sperm cells and eggs have 23 chromosomes, the haploid number. Once they fuse, the number doubles to 46 chromosomes. You may be confusing this with chromosome replication. In chromosome replication, the number of chromosomes does not double, but the number of strands double. (A single stranded chromosome turns into a double stranded chromosome.) However, it is still considered a single chromosome, but with identical sister chromatids. This replication occurs during the S-phase of the cell cycle, before mitosis or meiosis.
Is DNA double-stranded and helical?
DNA in its native form is double-stranded and helical.
Is DNA a single-stranded and if not what is?
no..it's double-stranded..
