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.
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as ribosomal RNA (rRNA) genes or transfer RNA (tRNA) genes, the product is a functional RNA.eneration of RNA from DNA is known as transcription. In other word transcription is the process of creating a complementary RNA copy of a sequence of DNA. During transcription, a DNA sequence is read by RNA polymerase, which produces a complementary, antiparallel RNA strand.
