Since DNA is a double helix, denaturation is the step required to separate the strands from each other by increasing the temperature. ... The drastic change in temperature causes the hydrogen bonds between strands to break and as a result the two strands separate. ... After the DNA sample has separated into single strands, it is annealed. ... Since the purpose of this whole procedure is not to copy the entire DNA but a specific piece of the DNA being studied; primers which are designed to target the region of DNA adjacent to our DNA sequence of interest attach to this part of the sampled DNA a...

The fact that the polypeptides are joined together only by hydrogen bonds means that they can easily be broken and the strands can separate for replication and protein synthesis which allows for information to be transferred. ... The DNA molecule unwinds with the help of the enzyme DNA helicase, which helps break hydrogen bonds between complementary base pairs and separate the two strands. ... The chromatids containing replicated DNA separate from each other and are redistributed as chromosomes in the nuclei of the two new daughter cells. ... Chromatids cross over and can exchange genetic ma...

It is the act of taking a piece of DNA and combining it with another organism's DNA to produce a new strand of DNA. ... Moreover, there are three stages in order to take to manipulate the genes in order to produce recombinant DNA which involves separating DNA strands into various pieces, the insertion of these pieces into the vector and lastly, introducing the vector into the bacterium since insulin is a protein. ...
