I just learned that IBM offers one way to read PLC data. I learned this on a different stack exchange site, but they showed how to read PLC data from a C++ application. Here is the link:
The determination of DNA sequences and the identification of the products generated by the fusion of complementary DNA sequences is widely used in the field of molecular biology, as well as in other fields such as medical research, molecular diagnostics, the development of new drugs, and in many other areas. Examples of these fields include the development of new types of drugs, new methods of diagnostics and treatments, the identification of the molecular basis of diseases, the preparation of genetically modified organisms, and the preparation of synthetic genes for therapeutic or other purposes. In each of these fields, a large number of different sequences of DNA must be analyzed in order to make progress.
DNA sequencing is a widely used technique for analyzing DNA. Briefly, DNA is first separated into two or more complementary strands which are then sequenced. The first step of this process is typically cleavage of the DNA by a restriction enzyme that makes precise cuts at individual recognition sites along the DNA. The recognition sites are usually four base pairs in length, and there may be many restriction sites spaced at intervals along the DNA. Thus, the recognition sites can be used to map the DNA. After the separation of the strands, one or both of the strands are then labeled. A series of chemical reactions is then carried out to generate single- and double-stranded DNA molecules, each labeled with a marker at a known location along the DNA. Each of these molecules has a specific base sequence and a label at a known position. By using the DNA in various ways, the labeled nucleotides are generated and used to form a double-stranded DNA molecule that can be separated on the basis of size by gel electrophoresis, or can be used in a hybridization reaction. In a hybridization reaction, each of the strands of the DNA is hybridized with a single-stranded nucleic acid probe under conditions that allow only the strand that is complementary to the probe to be hybridized to it. The identity of the strand is then determined by the sequence of the marker or
