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.
Most splicing occurs between exons on a single RNA transcript, but occasionally trans-splicing occurs, in which exons on different pre-mRNAs are ligated together. The splicing process occurs in cellular machines called spliceosomes, in which the snRNPs are found along with additional proteins.igure 1: Pre-mRNA splicing. Splicing of a pre-mRNA molecule occurs in several steps that are catalyzed by small nuclear ribonucleoproteins (snRNPs). After the U1 snRNP binds to the 5â² splice site, the 5â² end of the intron base pairs with the downstream branch sequence, forming a lariat.
