Ligation is the process of joining two DNA fragments or other molecules by a phosphate ester linkage with the action of enzyme. Ligation of DNA is process that involve the DNA of interest is inserted into the plasmid. This 3’-hydroxyl of DNA terminus are joined together with 5’-phosphoryl of another by phosphodiester bond. The ligation of DNA fragments usually performed by using T4 DNA ligase. All the reaction components such as ligation buffer‚ DNA insert‚ pGEM®-T‚ and T4 DNA ligase is mixed by

According to the website www.tutorvista.com‚ Prokaryotes differ from eukaryotes in their structure‚ packing‚ density‚ and arrangement of their genes on the chromosome. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the cell wall‚ and the structure of chromosomal DNA. All cells share some common characteristics that make them living things and all organisms are composed of cells which are the basic fundamental unit of life.

Recombinant DNA Technology‚ scientists are able to produce such insulin in laboratories. The process for creating this insulin starts with isolating the gene from the human cells. Then after it has been isolated‚ it is then inserted into plasmids. From there the plasmids are introduced into bacterial cells. These cells manufacture the insulin protein based on the human code. The final‚ purified product is identical to human insulin and non-allergenic. In some cases though‚ yeast is used in recombinant
