The PCR product are precipitated before sequencing to increase the concentration of tamplet DNA.
Template DNA is a DNA you want to amplify. So you should know what you are amplifying before a PCR or you can make it by sequencing your PCR product.
TA Cloning is one of the most popular methods of cloning the amplified PCR product using Taq and other polymerases. These polymerases lack 5'-3' proofreading activity and are capable of adding adenosine triphosphate residue to the 3' ends of the double stranded PCR product. Such PCR amplified product can be cloned in a linearized vector with complementary 3' T overhangs. TA cloning is brought about by the terminal transferase activity of certain type of DNA polymerase such as the Taq polymerase. This enzyme adds a single, 3'-A overhang to each end of the PCR product. As a result, the PCR product can be directly cloned into a linearized cloning vector that have single base 3'-T overhangs on each end. Such vectors are called T- vectors. The PCR product with A overhang, is mixed with this vector in high proportion. The complementary overhangs of a "T" vector and the PCR product hybridize. The result is a recombinant DNA, the recombination being brought about by DNA ligase.

PCR is a biotechnological method to amplify your gene (DNA) of your interest. It produce millions of your DNA fragments hence used in cloning. There are variants of this method using the same thermocycling principle such as touch down PCR, gradient PCR, RFLP, multiplex PCR, Q PCR, RT PCR and so on.

The First discrete PCR product will be found in the 3rd round.

PCR allows amplification of DNA for a specific gene, after too many cycles of PCR the result will reach saturation, basically meaning all of the DNA has been amplified. Conventional PCR will basically tell you whether or not a gene is expressed in your sample. This can be done semi-quantitavely if the PCR is performed for a low number of cycles, ie it will tell you whether one sample expresses more of your gene of interest than another sample. The results are seen by separating the PCR products by agarose gel/ethidium bromide electrophoresis. Real-time PCR will record exactly what cycle of PCR a detectable level of amplified product became detectable, giving a far more accurately quantifiable estimation of gene expression.
types of pcr: AFLP -PCR. Allele-specific PCR. Alu-PCR. Assembly -PCR. Assemetric -PCR. Colony -PCR. Helicase dependent amplification. Hot start pCR. Inverse -PCR. Insitu -pCR. ISSR-PCR. RT-PCR(REVERSE TARNSCRIPTASE). REAL TIME -PCR

It all depends on where you primers are. Presumably you will have one primer that sits on the cloned gene and one that sits on the vector (that way you only get a product if the gene has cloned successfully). As long as you know where your primers land, it should be easy to work out how big the PCR product will be simply by adding the distance from the primer on the gene to the end of the gene and the distance from the primer on the vector to the end of the vector.
Primerdimer occur, when the Primer are -or parts- are complementary (3' of the FOR- and 3' of the REV-Primer). While PCR both oligos hybridizate and are elongated. The Product contains both primer sequences. Primerdimers reduce the avaiable ammount of primers for the pcr-reaction. Therefore the pcr effectivity is reduced because of this non-specific reaction.

Real time PCR has been around for over twenty five years. It was revolutionized in the mid 1980's. Real time PCR helps view how much is increased in a DNA sample.
