The report uses the twenty-component Fe8L12 supra-molecule to describe the techniques of branched knot formation through metallo-supra-molecular assembly. DNA Knots and Polyhedrals in DNA Nanotechnology DNA is a double stranded polynucleotide. It contains biological information and regulates the functions of a cell as well as determining an organism’s phenotype. Knots are found in both DNA and some proteins (Jean.F et al. 2011).
A few years later, GMMs which produced essential human proteins were churned out by researchers (Teisha, 2013). Insulin, interferons (IFNs), and interleukins are among the famous proteins that are now produced by GMMs for therapeutic purpose. Human insulin was produced by genetically modified E. coli with exogenous human insulin genes inserted (Johnson, 1983). Besides, human growth hormone is also produced by modified E. coli containing the native human growth hormone genes (Cronin, 1997). The gene which encodes IFN γ was introduced into E. coli under regulation of tryptophan promoter and operator cassette (Lei, 2004).

The genetic information of an organism allows for the continuation of life. This genetic information is passed from parent to offspring via the molecule deoxyribonucleic acid (DNA). The structure of the DNA molecule provides a solution for the replication of the existing DNA molecule and furthermore the transmission of heritable information to the next generation. The scope of this essay will discuss how the molecular structure of DNA allows for DNA to replicate and transmit heritable information from one generation to the next. In 1958 Frank Stahl and Matthew Meselson discovered the complementary base pairing between DNA strands and that the process of DNA replication is semi-conservative.

Living cells contain two kinds of nucleic acids-ribonucleic acid (RNA) which contains the sugar, ribose and deoxyribonucleic (DNA) which contains the sugar, deoxyribose. Nucleic acids are found in all living things, from the simplest protozoan to the most complex forms of animal and plant life . Two young scientists-James Watson and Francis Crick-finally pieced together the precise structure of DNA. The model proposed by Watson and Crick for the structure of DNA is shaped like a twisted ladder. This type of figure is known as a double helix.

Two of which are gel electrophoresis and autoradiography. In 1950, a scientist named Oliver Smithies invented gel electrophoresis. So, what is gel electrophoresis? It is the process of separating molecules of either nucleic acids or proteins based on their size, electric charge, and their other physical properties. With the use of restriction fragment length polymorphism (RFLP) technology in DNA fingerprinting, the sorted double-stranded DNA fragments were then subjected to a blotting technique in which they were split into single strands and transferred to a nylon sheet.
