Gene splicing

A single locus can yield various differently spliced variants of mRNA, which are then translated into functionally different proteins. Individual genes encode specific proteins and it is estimated that there are approximately 50, genes in each cell of the human body.

gene splicing pros and cons

The coding region of a gene can be changed with naturally occurring or artificial mutations. Gene splicing can also specifically refer to a step during the processing of deoxyribonucleic acid DNA to prepare it to be translated into protein. The highly parallel and sensitive nature of microarrays make them ideal for monitoring gene expression on a tissue-specific, genome-wide level.

The problem with this is that sometimes bits of the bacteria DNA can end up in the final product or the Cas9 itself winding up in the genome of the final plant. Gene therapy, an active topic of research, provides a new and customized way to fight genetic diseases.

Scientists perform gene splicing in the lab and insert the DNA into plants, animals or cell lines. Gene splicing is a form of genetic engineering where specific genes or gene sequences are inserted into the genome of a different organism.

Gene splicing wikipedia

The DNA must first be processed into a form that other molecules in the cell can recognize and translate it into the appropriate protein. The problem with this is that sometimes bits of the bacteria DNA can end up in the final product or the Cas9 itself winding up in the genome of the final plant. This is a powerful approach and can be effectively used for analyzing a small number of genes. Then, researchers check the new sequence to make sure that its position and orientation in the DNA molecule are correct. Non-coding regions are equally important in determining gene function. 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. Microarray Based Gene Splicing Detection The use of microarray technology is not uncommon for researchers involved in large scale studies of alternative splicing. These splicing factors are serine rich and select splice sites in two modes: RS arginine-serine domain dependent and RS domain independent. Individual genes encode specific proteins and it is estimated that there are approximately 50, genes in each cell of the human body. Although the genetic information is, for the most part, the same in both cell types, the different functional purposes result in different cellular needs and therefore different proteins are produced in different tissue types. Promoter sequences control the ways that genes are expressed in a cell. Because the cellular functions in different tissues have varying purposes, the genes undergo a complex concerted effort to maintain the appropriate level of gene expression in a tissue specific manner. CRISPR is, of course, a means of guiding a gene editing platform to a particular place within a genome using RNA—the idea is to remove parts of a genome that are undesirable or to replace them with parts that are, to produce a plant or animal with desirable characteristics. These enhancer and suppressor regions are identified on the pre-mRNA by some proteins known as splicing factors which bind to these regions. This gives them the freedom to detect the junctions between the exon-exon combinations, exon-intron combinations and the splice variants, as well as the length of exon.

The gene splicing mechanism retains the non-coding junk portions of the gene and leads to a demornity in the protein structure and functionality. Gene splicing provides a sound experimental basis in support of the multiple proteins per gene theory.

They add new genes to organisms to make crop plants disease resistant or more nutritious. Microarray based splice variant detection is the most popular method currently in use.
