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

What property of DNA makes it possible for a probe to find a single-stranded DNA target gene?
a DNA molecule has two paired strands. ~
How many strands is DNA made of?
DNA is composed of two strands of DNA nucleotides.
DNA molecules has how many strands?
DNA molecule is normally double stranded
How many strands of RNA are transcribed from the two unzipped strands of DNA?
One
At the end of DNA replication two new strands of DNA have been produced giving a total of?
Two new DNA chains are formed at the end of DNA replication, both identical in sequence to the template (or parent) chain. These chains are composed of 2 complimentary strands. It is important to note that of the newly formed DNA chains, one strand is the same as the template strand and the other one is a newly synthesized one.
Where do you get your RNA?
Dna is split up into two different strands of nucleotides. After that is beyond me.
What are the two strands DNA held by?
The two strands of DNA are connected by hydrogen bonds.
What property of DNA makes it possible for a probe to find a single-stranded DNA target gene?
a DNA molecule has two paired strands. ~
How many strands are there at the beginning of DNA replication?
At the beginning of DNA replication there are two strands of DNA nucleotides.
If the DNA strands are matched up what does that mean?
This means the two strands of DNA are complementary.
What type of DNA molecule forms as a result o DNA replication?
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.
Why do scientists only need a tiny trace of DNA for tests?
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.
What is the result when DNA ligase has completed its job?
Two new strands of DNA. <--- Gradpoint/NovaNet
What is the processes of replication?
DNA replication simply means that DNA will split the double helix in two and refill its self. which then will make two of the same DNA strands.
How many strands is DNA made of?
DNA is composed of two strands of DNA nucleotides.
DNA molecules has how many strands?
DNA molecule is normally double stranded
What type of bonding holds the two strands of DNA together and why is this important?
hydrogen bonding between the two bases present on two strands of dna hold the two strands. If there was no hydrogen bonding then doublex helix structure of dna would not be possible
