What are the best ways to reduce generation of chimeric molecules during PCR?

The chimeric molecules generated during PCR are really bad for our study on recombination, since the chimeras look exactly like recombination. I wonder what and how (would be better if protocol is...

What percent of template can be synthesized during PCR?

For example, the parameters for PCR are denaturing at 95, annealing at 58 and elongation at 72, while the melting temperatures of primers are around 60.

Is there a way to reduce the interference from genomic DNA on your template-primer pairing?

For example, whether long DNA fragments or shorter ones (such as with restriction enzymes) interfere with the pairing of the primers to the templates of interest with different efficiency or not.

Does anyone have experience about the efficiency for linear DNA synthesis?

We are trying to synthesize mouse DNA using "linear" synthesis in very limited number of cycles without "denaturing". Do you have any experience for linear DNA synthesis, especially about the the...

How likely DNA double strands are seperated (melted) at lower than melting temperature?

For example, how many percent (if any) of DNA is melted at 5 degree lower than the melting temperature? Thanks.

How do you think about "DNA toxicity"?

I mean the toxicity is based on DNA sequence or its structure per se not the transcription or expression products from the DNA.

Is digestion of genomic DNA helpful to increase the pairing of primer to a specific genomic region of interest?

We are trying to test the efficiency of pairing of a primer to a region of mouse genome. We are thinking of digesting genomic DNA before pairing and wonder whether the longer or the shorter...

Do you know of any high-yield genomic DNA extraction kit/protocol?

I am trying to extract genomic DNA from a small pool of mouse cells (around 60,000 cells) and the yield is critical for me (at least 80%). Does anyone have good suggestions for which genomic DNA...
