Gene splicing is the process of taking fragments from DNA . One benefit of gene splicing could be to alter the health of an ill person by using the splicing technique to manipulate the unhealthy genes.
Gene splicing is used for important efforts such as the production of insulin.
In the past, insulin was only accessible from the pancreas of cadavers*, (50 cadavers = 1 dose!). With today's splicing techniques, enough insulin can be provided for all diabetics. Insulin-producing genes from human DNA are spliced into plasmid DNA. Then, plasmids are allowed to infect bacteria. As the bacteria multiply, insulin is then produced in a large, harvestable state.
Gene Splicing Mechanism In natural condition in eukaryotic cells:
There are several types of common gene splicing events. These are the events that can simultaneously occur in the genes after the mRNA is formed from the transcription step of the central dogma of molecular Biology.
Exon Skipping: This is the most common known gene splicing mechanism in which exon(s) are included or excluded from the final gene transcript leading to extended or shortened mRNA variants. The exons are the coding regions of a gene and are responsible for producing proteins that are utilized in various cell types for a number of functions.
Intron Retention: An event in which an intron is retained in the final transcript. In humans 2-5 % of the genes have been reported to retain introns. The gene splicing mechanism retains the non-coding (junk) portions of the gene and leads to a demornity in the protein structure and functionality.
Alternative 3' splice site and 5' splice site: Alternative gene splicing includes joining of different 5' and 3' splice site. In this kind of gene splicing, two or more alternative 5' splice site compete for joining to two or more alternate 3' splice site.
In artificial condition it can be done as following procedure:
Chemicals called restriction enzymes act as the scissors to cut the DNA. Thousands of varieties of restriction enzymes exist, each recognizing only a single nucleotide sequence. Once it finds that sequence in a strand of DNA, it attacks it and splits the base pairs apart, leaving single helix strands at the end of two double helixes. Scientists are then free to add any genetic sequences they wish into the broken chain and, afterwards, the chain is repaired (as a longer chain with the added DNA) with another enzyme called ligase. Hence, any form of genetic material can be spliced together; bacteria and chicken DNA can, and have been, combined. More often, though, splicing is used for important efforts such as the production of insulin and growth hormone to cure human maladies. In the past, insulin was only obtainable from the pancreas of cadavers (and it required 50 cadavers to yield one dose!).
In natural conditin in a eukaryotic cell it is done so as to remove the gene part which does not code for any protein and are called exons and to join the rest parts which are known as introns so as to make gene more specific and meaningfull
In laboratory condition it is done to insert a new type of gene in other organism by means of plasmid or other method
Well splicing does help create insulin, there's an advantage. It also helps to make produce better.
Alternative splicing is a process that occurs during gene expression. It allows for the production of multiple proteins from a single gene coding.
Gene splicing is the method of cutting out a part of the DNA in a gene and adding a new DNA in it's place.
you get a new variety of species using artificial selection

Some disadvantages of Gene Splicing, is that we spend about 40 million every year on it, when we could be spending it in schools. Teachers are being laid off by the dozens, because of the economic downfall, while, that much money is being spent on Gene splicing.

An alternative RNA splicing is a process by which the exons of the RNA produced by the transcription of a gene are reconnected in multiple ways during RNA splicing, so as to allow production of multiple forms of protein from one gene.

Cloning and gene splicing are are highly advanced, if not outright dangerous, practices of biology.

Gene splicing means cutting of gene in fragments and rejoining them according to need There are two phenomenon by which gene splicing occur one is natural i.e. post transcriptional modification and other is artifically or by chemical agent used generally in recombinant technologyPOST TRANSCRIPTIONAL MODIFICATION: Gene splicing is a post-transcriptional modification in which a single gene can code for multiple proteins. Gene Splicing is done in eukaryotes, prior to mRNA translation, by the differential inclusion or exclusion of regions of pre-mRNA. Gene splicing is an important source of protein diversity. During a typical gene splicing event, the pre-mRNA transcribed from one gene can lead to different mature mRNA molecules that generate multiple functional proteins. Thus, gene splicing enables a single gene to increase its coding capacity, allowing the synthesis of protein isoforms that are structurally and functionally distinct. Gene splicing is observed in high proportion of genes. In human cells, about 40-60% of the genes are known to exhibit alternative splicing.Gene Splicing MechanismThere are several types of common gene splicing events.

In this kind of gene splicing, two or more alternative 5' splice site compete for joining to two or more alternate 3' splice site.A gene-sized fragment of DNA is isolated from another organism. The bases of the fragment are spliced (joined) to the bases of the molecule by using a chemical called ligase.
Because DNA cannot fit through the pores of the nuclear membrane, it is too big, the mRNA copies off the specific parts needed and sends the information to where the body needs them. Without mRNA, you could not function properly.
Splicing is when you take two things and put them together. For example you can splice a piece of rope with another piece of rope. You can also do this in genetics by gene splicing.
