Fundamentals of Molecular Similarity

Researchers have started to study the role of symbiotic organisms in the biosynthesis of natural products of marine invertebrates. The possibility of molecular microbiology to produce basic biological discoveries is attractive and the possibility of increasing the availability of these other difficult to obtain compounds is a major outcome in microbial biotechnology I guess. Research on symbiosis of invertebrates' natural products is expected to become an exciting new field of molecular microbiology

Molecular cloning is similar to polymerase chain reaction (PCR) in that it permits replication of DNA sequences. The fundamental difference between the two methods is that molecular cloning involves the replication of DNA in live microorganisms, while PCR replicates DNA in vitro without viable cells. In standard molecular cloning experiments, the cloning of any DNA fragment basically consists of seven steps: (1) selection of host organism and cloning vector, (2) preparation of vector DNA, (3) cloning DNA (5) introducing the recombinant DNA into the host organism, (6) selecting the organism containing the recombinant DNA, and (7) selecting the desired DNA insert and organism Screen clones with academic characteristics.

Molecular cloning takes advantage of the fact that the chemical structure of DNA is essentially the same in all organisms. Therefore, when an arbitrary DNA fragment derived from any organism is inserted into a DNA fragment containing a molecular sequence necessary for DNA replication and the obtained recombinant DNA is introduced into an organism to obtain a replication sequence, the foreign DNA is replicated. Along with the host cell DNA in the transgenic organism. Molecular cloning is similar to polymerase chain reaction (PCR) in that it permits replication of DNA sequences. The fundamental difference between the two methods is that molecular cloning involves replication of DNA in live microorganisms, while PCR replicates DNA in vitro without living cells.
