The procedure used to amplify DNA in vitro is called Polymerase Chain Reaction (PCR). It involves repeated cycles of denaturation, annealing, and extension, which allow for the selective amplification of specific DNA sequences. In each cycle, the DNA is heated to separate the strands, cooled to allow primers to bind, and then heated again for a DNA polymerase enzyme to synthesize new strands. This process can exponentially increase the amount of target DNA, making it useful for various applications in research and diagnostics.

The laboratory procedure for copying selected segments of DNA is?
The laboratory procedure for copying selected segments of DNA is called polymerase chain reaction (PCR). In PCR, the DNA template is heated to separate the DNA strands, then specific primers are added to initiate replication by a DNA polymerase enzyme. The process is repeated multiple times to amplify the DNA segments of interest.
What process is used to amplify small DNA samples?

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.
What is main function of DNA polymerase?
The DNA polymerase enzyme synthesises the complementary DNA strand to a single stranded DNA strand (in vivo and in vitro). This often requires the presence of a 3' end for the polymerase enzyme to bind to before synthesis can begin. Taq polymerase (A DNA polymerase) is often used in PCR reactions to synthesise DNA in vitro using primers to provide a 3' end to bind to.
How does DNA fingerprinting relate to Poly Chain Reaction?
DNA fingerprinting uses variants in DNA sequences to create a unique profile for each individual, while the Polymerase Chain Reaction (PCR) is a technique used to amplify specific DNA sequences. PCR is commonly used in DNA fingerprinting to amplify regions of interest in the DNA sample before further analysis. This amplification step allows for better detection and characterization of DNA variations used in DNA fingerprinting.
Process used to amplify small DNA samples?
Polymerase chain reaction (PCR) is a commonly used method to amplify small DNA samples. In PCR, the DNA sample is heated to separate the double-stranded DNA into single strands, then specific primers are added to flank the target DNA sequence. DNA polymerase then synthesizes new DNA strands complementary to the target sequence, resulting in exponential amplification of the DNA fragment.
How are restriction enzymes used in PCR?
Restriction enzymes are not typically used in PCR. PCR relies on DNA polymerase to amplify specific DNA sequences, while restriction enzymes are used to cut DNA at specific recognition sites for other applications, such as cloning.
In preparation for electrophoresis procedure enzymes are added to DNA in order to?
In preparation for electrophoresis, enzymes such as restriction enzymes are added to DNA to cut it at specific sequences, resulting in fragments of varying lengths. This fragmentation is essential for analyzing the DNA, as it allows for differentiation based on size during the electrophoresis process. Additionally, enzymes like DNA polymerases may be used to amplify specific regions of interest, enhancing the visibility of the DNA bands after separation.
What does polymerase chain reaction enable scientist to make?
Polymerase chain reaction (PCR) enables scientists to make millions of copies of a specific DNA sequence in a short amount of time. This technique is commonly used in research, forensics, and medical diagnostics to amplify DNA for analysis.
How is PCR used in conjunction with gel electrophoresis to analyze DNA samples?
Polymerase chain reaction (PCR) is used to amplify specific regions of DNA in a sample. Gel electrophoresis is then used to separate the amplified DNA fragments based on size. By comparing the resulting DNA bands on the gel, scientists can analyze and identify the DNA samples.
Which two methods are most often used in DNA fingerprinting?
The two most often used methods in DNA fingerprinting are polymerase chain reaction (PCR) and gel electrophoresis. PCR is used to amplify the DNA samples, while gel electrophoresis is used to separate the DNA fragments based on their size.
