FAQ
The final stage is the extension step (20 sec to 1 min at 72 °C), which is performed so that the DNA polymerase extends the primer sequences from the 3' of each primer to the end of the amplicon. A 1 min extension is typically sufficient to synthesize PCR fragments up to 2 kilobases (kb).
The filing of this application on or before the due date automatically provides an extension of six months after such due date for the filing of your completed tax return, provided the tax is properly estimated and the application is accompanied by a remittance for the amount shown on line 6.
Extended Deadline with New York Tax Extension: New York State offers a 6-month extension, which moves the individual filing deadline from April 15 to October 15 (for calendar year filers). New York Tax Extension Form: To apply for a New York extension, file Form IT-370 by the original due date of your return.
New York does not recognize a federal extension.
Extension Time Extensions are normally performed at 68°C. As a general rule, use extension times of one minute per 1000 base pairs (e.g. 3 minutes for a 3 kb product) For products less than 1 kb, use 45-60 seconds. Products greater than 3 kb, or reactions using more than 30 cycles, may require longer extensions.

During the extension step (typically 68-72°C) the polymerase extends the primer to form a nascent DNA strand. This process is repeated multiple times (typically 25-35 cycles), and because each new strand can also serve as a template for the primers, the region of interest is amplified exponentially.
If the extension time is too short, there will be insufficient time for complete replication of the target. Generally, use an extension time of 1 min/kb. If the annealing time is too short, primers do not have enough time to bind to the template. Use an annealing time of at least 30 sec.
Duration of extension will be dependent upon amplicon size (30 sec per 1 kb). The period of elongation depends upon the desired length of the amplicon and the enzyme used. Since qPCR amplicons are short, this is typically 5–30 sec.
Step : 3 Extension Generally, the reaction mixture is heated to a temperature intermediate between denaturation and annealing at this stage. 72°C is the ideal temperature for Taq polymerase. The polymerase extends the primers from 5' to 3'.

Primer extension typically occurs at a temperature ranging from 68-72°C. Repeat steps 2-4 25-30 times.Final Extension for 5 minutes at 72°C: A final extension to fill-in any protruding ends of the newly synthesized strands. In general, 1 min per kb is very practical as duration of extension time. There could be a lot of other issues if you are not getting a band. The recommended extension temperature is 72°C. Repeat steps 2-4 25-30 times. Final Extension for 5 minutes at 72°C: A final extension to fill-in any protruding ends of the newly synthesized strands. PCR products up to 500 bp. It's the latter the primers continue to anneal during the extension step because it is a 2step PCR (98°C 15sec, 65°C 5 mins).
