- Life Science & Laboratory DNA Sequencing / Analysis Systems Equipment. DNA sequencing is the process used for determining the order of the nucleotide bases—adenine, guanine, cytosine, and thymine—in a molecule of DNA. DNA sequencers are scientific instruments used to automate the DNA sequencing process.

- 1 If the genomic DNA sequence of a gene is known, RT-PCR can be used to map the location of exons and introns in the gene. 2  The 5' end of a gene (corresponding to the transcription start site) is typically identified by RACE-PCR (Rapid Amplification of cDNA Ends).

Restriction Fragment Length Polymorphism (RFLP) PCR-RFLP. Isolation of sufficient DNA for RFLP analysis is time consuming and labor intensive. However, PCR can be used to amplify very small amounts of DNA, usually in 2-3 hours, to the levels required for RFLP analysis. Therefore, more samples can be analyzed in a shorter time.An alternative name for the technique is Cleaved Amplified Polymorphic Sequence (CAPS) assay.s a difference in homologous DNA sequences that can be detected by the presence of fragments of different lengths after digestion of the DNA samples in question with specific restriction endonucleases.

- DNA ligation. In cells and in the lab, enzymes called ligases are used to join fragments of DNA together. Only DNA fragments that have matching, complementary ends can be joined by ligation.

Polymerase chain reaction PCR amplifies a specific region of a DNA strand (the DNA target). Most PCR methods typically amplify DNA fragments of between 0.1 and 10 kilo base pairs (kbp), although some techniques allow for amplification of fragments up to 40 kbp in size.The amount of amplified product is determined by the available substrates in the reaction, which become limiting as the reaction progresses. If the genomic DNA sequence of a gene is known, RT-PCR can be used to map the location of exons and introns in the gene. 2  The 5' end of a gene (corresponding to the transcription start site) is typically identified by RACE-PCR (Rapid Amplification of cDNA Ends).

Hybridization probe (December 2009). In molecular biology, X hybridization probe is a fragment of DNA or RNA of variable length (usually 100-1000 bases long) which is radioactively labeled.It can then be used in DNA or RNA samples to detect the presence of nucleotide sequences (the DNA target) that are complementary to the sequence in the probe.ybridization probes used in DNA microarrays refer to DNA covalently attached to an inert surface, such as coated glass slides or gene chips, to which a mobile cDNA target is hybridized.

DNA microarray A DNA microarray (also commonly known as DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface.Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome.Each DNA spot contains picomoles (10 −12 moles) of a specific DNA sequence, known as probes (or reporters or oligos).he two Cy-labeled cDNA samples are mixed and hybridized to a single microarray that is then scanned in a microarray scanner to visualize fluorescence of the two fluorophores after excitation with a laser beam of a defined wavelength.

DNA Analysis It is one of the most significant advances in science. The process involves copying a portion of DNA with a small molecular machine called polymerase, an enzyme, to duplicate DNA regions in a test tube. The process can be repeated to produce billions of DNA molecules in a few hours. Unlike other types of analysis, this DNA analysis process can reproduce DNA using a tiny sample of cells.

Polymerase chain reaction 1 In silico PCR (digital PCR, virtual PCR, electronic PCR, e-PCR) refers to computational tools used to calculate theoretical polymerase chain reaction results using a given set of primers (probes) to amplify DNA sequences from a sequenced genome or transcriptome.

- Restriction Enzymes. Restriction enzymes, also known as restriction endonucleases, are enzymes that cut a DNA molecule at a particular place. They are essential tools for recombinant DNA technology. The enzyme scans a DNA molecule, looking for a particular sequence, usually of four to six nucleotides.

- Microarrays are a collection of many short DNA strands, called “probes,” that are attached to a solid surface (e.g., a glass slide). The probes are selected for their specific, known DNA sequenceto which, only complementary pieces of DNA will bind (hybridize).

DNA Testing Procedures The DNA testing process is comprised of four main steps, including extraction, quantitation, amplification, and capillary electrophoresis. Extraction. DNA is located within the nucleus of cells throughout the body and the extraction step is responsible for breaking open the nucleus and releasing the DNA molecules into solution.

- DNA extraction. DNA (DeoxyriboNucleic Acid) is a long stringy molecule that can be extracted from any biological material such as living or conserved tissues, cells and virus particles.A number of basic procedures are carried out to isolate and purify DNA.First the cell is broken open to expose its DNA. This is achieved by blending or grinding the cell. The next step involves breaking down and emulsifying the fat and proteins that make up the cell's membrane.NA extraction. DNA (DeoxyriboNucleic Acid) is a long stringy molecule that can be extracted from any biological material such as living or conserved tissues, cells and virus particles.
