A recent article titled Natural gas: A modern fuel millions of years in the making reported that the refined gas used in barbecue grills marks the last step in a process that began more than 500 million years ago. 1. But that's not so. Natural gas can be produced by adding heat and water to brown coal.
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule.It includes any method or technology that is used to determine the order of the four basesâ adenine, guanine, cytosine, and thymine âin a strand of DNA.The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery.NA sequencing is the determination of the physical order of these bases in a molecule of DNA. However, there are many other bases that may be present in a molecule. In some viruses (specifically, bacteriophage), cytosine may be replaced by hydroxy methyl or hydroxy methyl glucose cytosine.
Definition of Gene Splicing. Gene splicing is the procedure where pieces of DNA are cut up and spliced together to form recombinant DNA. The DNA fragments usually come from different organisms. The DNA molecules are not cut by a physical pair of scissors; the process is enzymatic with the target DNA being chemically cut by restriction enzymes.
