Where are the presumed millions of years supposed to fit in this timeline? Articles such as the one listed above present eons-long fossil fuel formation as undisputed fact. But both science and the Bible indicate that oil and gas were not millions of years in the making, but are only thousands of years old.
Gene splicing first came to worldwide attention in 1973 with the creation of the first genetically engineered organism. 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.
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.Â© 2013 Nature Education All rights reserved.n the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.
