DNA Sequencing is the procedure of determining the sequence of a particular nucleic acid - the sequence of DNA bases. It involves any modern technique that determines the sequence of the four bases adenine, cytosine, guanine, and thymine (which are also called as A, C, G, and T). It is generally undertaken to determine inherited characteristics in humans such as diseases, sexual identity and genotypes. The most popular method of DNA Sequencing is Polymerase Chain Reaction (PCR). In this method, DNA molecules are heated, and when one of these molecules sticks to another, the resulting sequence is measured, and a specific DNA sequence is determined.

The modern techniques used in this method include PCR amplification, NGS, BAC, Genome Analysis by Hybridization (GAH), and other methods. The PCR method uses a DNA template and probes for amplification and sequence determination. The next step is called BAC or Bonnet Binding Assay. This method uses two separate DNA templates. The first DNA template has a probe, which are then inserted into the second template, and the results are measured. The GAH method is a relatively new method and involves placing DNA sequence tags on the DNA sequences, thus enabling the analysis to be performed easily.

Another method in DNA Sequencing, is the Genome Analysis by Hybridization (GAH) method. This method works by using a sample of DNA to amplify a specific DNA sequence that is needed for certain research purposes, and then the amplified sequence is used for genetic mapping of a person's DNA sequence, for instance, in medical research. In this way, it is possible to get accurate genetic information about a person by his genetic markers. Genomics is a more recent term for genetic analysis, which basically means analyzing genetic data to answer questions about health or disease.
There are several types of DNA sequencing laboratories, where scientists perform sequencing using different methods depending on the type of sequence that is being studied. There are DNA laboratories, and DNA libraries where the samples of DNA are collected and sequenced.
Before DNA sequencing became an important scientific endeavor, people had to wait for years to see their results. It used to take a long time before they could read the information from their samples. But the advent of DNA sequencing made it much easier. It took only a few decades to be able to read the sequence of a single base pair of DNA, and even shorter times for more complicated sequences. Now, we can read the sequence of many bases of DNA from a sample and determine the DNA sequence in a short period of time.
The advantages of DNA sequencing are many, including the ability to conduct genetic analysis in a short time. It also has become quite cheap. Today, people can perform DNA analysis without the use of a lab and get the results back quickly, which makes it feasible to do genealogical studies.
