FAQ
Ask for an extension in person, by phone or in writing. (See contact info on the Traffic Courthouse Locations page .) The Clerk can only give you one extension ("continuance") and only for cases that are set for arraignment or court trial and the matter was not set by the Court.
Six Ways to Resolve a California Traffic Ticket Hire an Attorney. Appear in Court to Request a Trial. Request a Trial by Written Declaration. Plead Guilty by Paying the Citation. Plead Guilty by Paying the Citation in Installments. Plead Guilty by Requesting Community Service.
If you need to postpone (a continuance or an extension) your arraignment (the date at the bottom of your ticket or on your courtesy Violation Information Notice), you may do so by phone, online, or in person at any of the court locations in the Traffic Division.

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.
Final Extension A post-PCR final incubation step of 5–10 min at 72°C is often recommended to promote complete synthesis of all PCR products.
A typical PCR cycle includes an extension step at 72°C after denaturation of double-stranded DNA and annealing of oligonucleotide primers. At this temperature the thermostable poly-merase replicates the DNA at an optimal rate that depends on the buffer and nature of the DNA template ( 1 ).
The extension time of PCR depends upon the synthesis rate of DNA polymerase and the length of target DNA. The typical extension time for Taq DNA Polymerase is 1 min/kb, whereas that of Pfu DNA polymerase is 2 min/kb.
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.
Increasing the final extension time improves full-length replication and yield of a 0.7-kb, GC-rich PCR fragment from human gDNA in these experiments. The smear under the desired band in 0 minute final extension suggests incomplete extension of the PCR amplicon by the DNA polymerase.
