Advantages of gene splicing

Answer 1

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.

Answer 2

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.

Answer 3

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!).

Answer 4

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

Answer 5

Well splicing does help create insulin, there's an advantage. It also helps to make produce better.

Answer 6

Alternative splicing is a process that occurs during gene expression. It allows for the production of multiple proteins from a single gene coding.

Answer 7

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.

Answer 8

you get a new variety of species using artificial selection

Answer 9

Insulin
