These are called Single Stranded Dna or ssDna.
To split DNA strands to create doubles.
The answer depends on the circumstances! In a cell, during DNA replication or during translation, the two strands in a DNA molecule are separated by enzymes called topoisomerases and helicases. In a solution, the two strands of a DNA molecule can be separated by being heated. This is called DNA melting. See: http://en.wikipedia.org/wiki/DNA http://en.wikipedia.org/wiki/DNA_melting
Dna is split up into two different strands of nucleotides. After that is beyond me.
replication fork
Genes are arranged on twisted strands called DNA. DNA is housed in the nucleus and controls the cells functions and systems.
The DNA undergoes a process named PCR (Polymer Chain Reaction) once the scientists get a hold of the DNA. essentially the DNA double helix is unwound and is split into its two strands, and random nucleotides (or primers as they are called in this process) attach to the two open strands. These primers form hydrogen bonds with the DNA strands. due to this, there are now two strands of DNA rather than just one. scientists do this over and over again, until they have enough DNA to be able to test whatever they need to test on it.
DNA polymerase
chromatin
It splits down the middle due to the action of the enzyme helicase. This exposes the nitrogen bases on both strands of the DNA.
In a cell, the tangles of long strands of DNA form the
During DNA replication the two strands of the DNA helix split apart and the ribosome reads off the template strand producing an exact copy of this strand. Then RNA polymerase base pairs both of the strands, producing 2 semi-conservative strands.
There is no such thing called a DNA nucleus. I assume you mean DNA found in the nucleus. The DNA that's found in the nucleus are many DNA strands all bunched up.
