It occurs in the specific area of a chromosome known as the origins that contain a series of codes that attract helicase (Corazon, 2010).

What is important when you design primers? there are several considerations for primers design including primer length between 18 and 24 bases, Melting Temperature (Tm) , 3' sequence and guanine-cytosine content .  3. Describe how PCR is performed! ● step 1- DNA , tow primer (forward and reverse primer), dNTPs , and DNA polymerase enzyme mixed together in sutable tube.
In the Science January 2013 issue, Deng et al. present the structural basis for sequence specific binding of TALEs to the sense strand of the DNA using a crystal structure. They solved the crystal structures of an engineered TALE named dHax3, crystallized both, in its free form and in complex with the DNA at 2.4A resolution. This structure elucidates the molecular mechanism of TALE binding to DNA and provides a foundation for the rational design of DNA-specific TALEs with different effector domains for site-specific manipulations of the genome. Bacterial TALEs modulate the target gene expression in host cells by acting as transcriptional activators.
It can be used to tell how actively a gene works, whether it carries any mutations, and even aid in the human genome project, a long term project to map the entire human genome. The biochip is a square of glass about the area of a dime. It is carpeted with DNA probes. The probes are oligonucleotides, strands of DNA six to nine bases long. A long strand of DNA of an unknown sequence is to be tested to determine its sequence.
The nature of base pairing meant that if the two strands of a DNA molecule were separated, they could each serve as a template for the creation of a complementary strand by bringing in individual nucleotides to base pair with their complementary base on the template, and joining the new nucleotides together. Thus, each DNA molecule after replication would consist of one of the original strands plus one newly synthesized strand. This model of DNA replication is called semiconservative. Semiconservative was not the only model of DNA replication, however.
There are several applications for genetic engineering in microbiology as well as other fields of biology.It includes invitro mutagenesis,gene synthesis, Expressing eukaryotic genes in bacteria,production of transgenic plants and animals,gene therapy,screening for genetic diseases and forensic analysis.

This produces a population of molecules, each terminating at a different site. Running the products in each tube on a gel allows the determination of where each chain terminating dideoxynucleotide was incorporated. The DNA is visualized because the DNA primer to start the reaction is radioactive or some of the dNTPs are radioactive This procedure is now automated so that a computer reads the sequence.
