In the ordering, every three nucleotides during a row count as a triplet and code for one amino alkanoic acid. In the first step, DNA is digested with restriction enzymes and separated by gel electrophoresis (as discussed above). Genetic code is the term we use in the manner that the four bases of DNA-the A, C, G, and Ts-are strung together in a way that the ribosome, the cellular machinery, can read them and switch them into a protein. A Southern blot (also called a Southern Transfer) is named after Ed Southern, its inventor. In some viruses, RNA, in spite of DNA, carries genetic information. It is principally involved in the synthesis of proteins, that carry the messenger instructions from DNA, which itself contains the genetic instructions needed for the event and maintenance of life. Ribonucleic acid (RNA) is an essential biological macromolecule that exists all together in biological cells. DNA Primase is another enzyme that's essential in DNA replication. Within the replication, the complex is the enzyme DNA Helicase, so that they can be utilized as a template for replication. There are numerous origin sites, and when replication of DNA starts, these sites are mentioned as replication forks.
To isolate and identify desire gene of interest.DNA synthesis is commenced at particular points within the DNA strand referred to as ‘origins’, which are certain coding regions. Used for paternity testing, criminal identification, victim identification. DNA finger printing is an example of southern blotting. Southern blotting technique is used to detect DNA in given sample. The membrane bound DNA labelled with probe can be visualized under autoradiogram which give pattern of bands. The probe bind with complementary DNA on the membrane since all other non-specific binding site on the membrane has been blocked by BSA or casein. The labelled probe contains the complementary sequences to the gene of interest. This technique is based on the principle of separation of DNA fragments by gel electrophoresis and identified by labelled probe hybridization. The DNA bound to membrane is then treated with labelled probe Southern blotting is a hybridization technique for identification of particular size of DNA from the mixture of other similar molecules. Denaturation: Treating with HCl and NaOH. Gel electrophoresis: SDS gel electrophoresis. Restriction digest: by RE enzyme and amplification by PCR. The probes are labeled with a marker so that they can be detected after hybridization. A hybridization probe is a short (100-500bp), single stranded DNA. Separated DNA fragments after transferring on nylon membrane, the desired DNA is detected using specific DNA probe that is complementary to the desired DNA. Basically, the DNA fragments are separated on the basis of size and charge during electrophoresis. Southern blotting is a hybridization technique for identification of particular size of DNA from the mixture of other similar molecules. Southern blotting is an example of RFLP (restriction fragment length polymorphism). The results in the present study demonstrated that the PCR- southern-hybridization technique on the gene chip (OliproTM Porcine gene chip) is a sensitive tool for monitoring the porcine.
