In the PCR, high temperatures are used in order to separate both strands of DNA readily. Normal DNA polymerases would "melt" (denature) under these conditions, whereas Taq DNA Polymerase does not (short from Thermus aquaticus, a bacteria that lives in very hot submarine springs).
What else can I help you with?
Does PCR use RNA primers in its process?
No, PCR (polymerase chain reaction) uses DNA primers, not RNA primers, in its process.
What do we use primers for during pcr?
Primers are short single-stranded DNA sequences that are used in PCR to anneal to the target DNA and provide a starting point for DNA polymerase to amplify the target sequence. They define the specific region of DNA to be amplified and are essential for the amplification of the target DNA fragment.
How are primers made for PCR?
Primers for PCR are short, single-stranded DNA sequences that are designed to bind to specific regions of the target DNA. They are typically synthesized in a laboratory using automated DNA synthesis machines that assemble the nucleotides in the desired sequence. The primers are then purified and tested to ensure they are suitable for use in the PCR reaction.
What is the purpose of mgcl in pcr?
The enzyme DNA polymerase ( Taq polymerase) used in the PCR requires Mg 2+ ions for its functioning.These Ions act as cofactors for the enzyme . Hence the requirement for the use of Mg Cl2 in PCR reactions.
What is a Taqman Real Time PCR?
Taqman Real Time PCR is a technique used in molecular biology to quantify the amount of a specific DNA target present in a sample. It involves the use of specific probes that bind to the target DNA sequence and produce a fluorescent signal during amplification, allowing for real-time detection and quantification of the DNA target. This method is widely used in research, clinical diagnostics, and other applications requiring accurate quantification of DNA.
Why was it difficult to use DNA as evidence in a crime pcr was invented?
you need many copies of DNA for DNA fingerprinting
Why was it difficult to use DNA as evidence in a crime before PCR was inventes?
you need many copies of DNA for DNA fingerprinting
Does PCR use RNA primers in its process?
No, PCR (polymerase chain reaction) uses DNA primers, not RNA primers, in its process.
What process could you use to amplify the DNA in a bloodstain from a crime scene?
PCR
Is polymerase chain reaction used to amplify DNA from a fossil a fetal cell or a virus?
The PCR reaction can be used to amplify DNA from all three sources mentioned. PCR relies on the use of short stretches of DNA that are 6 - 12 bases long to attach to the target DNA (the source where the DNA is coming from) so that the polymerase enzyme can make copies of the target DNA. As long as these primers are available (they can be commercially purchased in many cases), PCR can be carries out on fetal cell DNA and viral DNA. Fossil DNA however, may have undergone degradation. DNA has to be of a certain purity for PCR to work. If the fossil DNA had degraded or broken down, PCR cannot be carried out.

Why is it difficult to use DNA as evidence in a crime before PCR was invented?
Before PCR was invented, it was difficult to use DNA as evidence in a crime because traditional methods required a large amount of DNA sample, which may not have been available or may have been contaminated. This made it challenging to obtain reliable DNA profiles for comparison. Additionally, the older techniques were more time-consuming and less sensitive than PCR, making the process of analyzing DNA evidence slower and less accurate.
Is Gel Electrophoresis used to make many copies of DNA?
no, it is used to separate different sized pieces of DNA using a gel and an electric current. Polymerase Chain Reaction (PCR) is the multiplication of DNA with the use of a PCR machine, enzymes and primers. The PCR machine allows the multiplication of DNA through temperature changes, activating each step of the reaction and copying DNA millions of times.
