gene splicing
Quick Summary
Gene splicing, also known as recombinant DNA technology, is the process of preparing DNA molecules from different sources to create a new, combined DNA molecule. This technology, pioneered in the early 1970s, involves cutting DNA into fragments using restriction enzymes and then rejoining them.123
In eukaryotic cells, gene splicing also refers to RNA splicing, where non-coding regions (introns) are removed from RNA, and the coding regions (exons) are joined together. This process is crucial for converting genetic information from DNA into proteins. Genetic engineering, which utilizes gene splicing, has led to the production of vital medical products like insulin and vaccines, as well as genetically modified organisms.43

…in a process called intron splicing. Molecular complexes called spliceosomes, which are composed of proteins and RNA, have RNA sequences that are complementary to the junction between introns and adjacent coding regions called exons. The intron is twisted into a loop and excised, and the exons are linked together. The…

…nucleotide sequences that direct intron splicing may result in an mRNA that still contains an intron. When translated, this extra RNA will almost certainly be meaningless at the protein level, and its extra length will lead to a functionless protein. Any mutation that results in a lack of function for…
