Gene therapy usually seeks to replace a defective gene in a cell with the correct one using a vector for delivery, often a virus. The result is the transformed cells will product the correct protein. Protein therapy usually refers to injecting a functional protein into a patient to compensate for its absence.

How long has gene splicing been done?
Gene splicing has been done since the 1970s when scientists developed the technique for manipulating DNA. Through gene splicing, specific genes can be inserted, deleted, or modified in an organism's genome. This technology has revolutionized fields such as genetic engineering and biotechnology.
What is the first step of gene splicing?
The first step of gene splicing is to identify and isolate the gene of interest from the donor organism. This is typically done using restriction enzymes to cut the DNA at specific sites.
What happens during rna splicing m?
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. 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.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.

Why RNA splicing important?
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.
What is the adjective for genes?
The adjective form for gene or genes is genetic. The noun gene can be used with other nouns (e.g. gene therapy, gene splicing) but it is acting as a noun adjunct rather than an adjective.
Can you give me a sentence with the word splicing?
Cloning and gene splicing are are highly advanced, if not outright dangerous, practices of biology.

Difference between gene therapy and protein therapy?
at the gene level gene therapy is done and at the the protein level protein therapy is done

Inserting working copies of a gene directly into the cells of a person with a genetic disorder is called what?
That process is called gene therapy. It involves inserting functional copies of a gene into the cells of a person with a genetic disorder to correct the genetic mutation causing the disorder.

What does splicing mean?
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.
How does alternative splicing work in the process of gene expression?
Alternative splicing is a process in gene expression where different combinations of exons (coding regions) within a gene can be included or excluded from the final messenger RNA (mRNA) transcript. This allows a single gene to produce multiple protein isoforms with different functions.
Are exons removed during the process of splicing in gene expression?
Yes, exons are not removed during the process of splicing in gene expression. Instead, introns are removed and exons are joined together to form the mature mRNA molecule.
How could gene therapy be used to treat cancer?
