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 else can I help you with?
How many strands are there in DNA?
DNA is made up of two strands.
How many strands does DNA have in its structure?
DNA has a double helix structure, meaning it has two strands.
How many strands are present in a typical DNA molecule?
A typical DNA molecule consists of two strands.
How many strands are typically found in the DNA molecule?
A DNA molecule typically consists of two strands.
Do two DNA strands need to be separated before DNA replication or transcription can occur?
Yes. Also, of the two strands of DNA, only one is the template that will be transcribed, while the other strand is a noncoding strand of DNA.
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.
How many strands are there in DNA?
DNA is made up of two 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.
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.
If the DNA strands are matched up what does that mean?
This means the two strands of DNA are complementary.
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.
What is the result when DNA ligase has completed its job?
Two new strands of DNA. <--- Gradpoint/NovaNet

A DNA molecule typically consists of two strands.
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
