- Gene targeting is a genetic technique that uses homologous recombination to change an endogenous gene. The method can be used to delete a gene, remove exons, add a gene, and introduce point mutations. Gene targeting can be permanent or conditional. Conditions can be a specific time during development / life of the organism or limitation to a specific tissue, for example. Gene targeting requires the creation of a specific vector for each gene of interest. However, it can be used for any gene, reg

Gene regulatory network Control process of a gene regulatory network. A gene (or genetic) regulatory network (GRN) is a collection of molecular regulators that interact with each other and with other substances in the cell to govern the gene expression levels of mRNA and proteins.

Definitions &Translations Small activating RNA molecules can induce target gene expression in a phenomenon referred to as dsRNA-induced transcriptional activation. Small double-stranded RNA, such as small interfering RNA and microRNA, have been found to be the trigger of an evolutionary conserved mechanism known as RNA interference.

- Gene expression is the process that transfers genetic information from a gene made of DNA to a functional gene product made of RNA or protein. Genetic Information flows from DNA to RNA by the process of transcription and then from RNA to protein by the process of translation. In order to ensure that the proper products are produced, gene expression is regulated at many different stages during and in between transcription and translation.

What Is Gene Expression? - Regulation, Analysis & Definition Definition of Gene Expression. A gene is a small piece of genetic material written in a code and called DNA. Each gene has within it a set of instructions for making molecules that organisms need to survive. Genes themselves cannot be used by an organism.he first step is for a transcription factor to bind to the DNA at a point upstream to the target gene. This initiation point is a sequence of DNA called a promoter region. Transcription is the process by which a transcript (mRNA) of the gene is created.

- As is apparent from the above discussion, a drug target is a key molecule involved in a particular metabolic or signal transduction pathway that is specific to a disease condition or a specific disease. However, the term ‘drug target’ itself has several limitations and is debated within the pharmaceutical industry.n this respect, several points should be kept in mind. First, a drug target is a relative concept. For starters, a drug target is, just like other biomolecules, also a biomolecule involved in a transduction pathway. The difference between the two is only in their location and role in the transduction pathway.

- The gene of interest is cloned into the multiple cloning site by digesting both plasmid and gene fragment with restriction enzymes that produce complementary ends. Once the plasmid has been transferred into the target organism the promoter sequence determines when the gene is transcribed.

Regulatory sequence A regulatory sequence is a segment of a nucleic acid molecule which is capable of increasing or decreasing the expression of specific genes within an organism.Regulation of gene expression is an essential feature of all living organisms and viruses.n DNA, regulation of gene expression normally happens at the level of RNA biosynthesis (transcription), and is accomplished through the sequence-specific binding of proteins (transcription factors) that activate or inhibit transcription. Transcription factors may act as activators, repressors, or both.

Repressor In molecular genetics, a repressor is a DNA-or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers.

tumor suppressor gene tumor suppressor gene. tumor suppressor gene. A gene that suppresses cellular proliferation. When inherited in a mutated state in which it is no longer suppressive, it is associated with the development of various cancers, including most familial cancers.

How is c-Myc an oncogene when it promotes apoptosis? Tumor-suppressor genes generally encode proteins that in one way or another inhibit cell proliferation. 1  Loss of one or more of these “brakes” contributes to the development of many cancers. Five broad classes of proteins are generally recognized as being encoded by tumor-suppressor genes:

Gene A gene is a locus (or region) of DNA that encodes a functional RNA or protein product, and is the molecular unit of heredity. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits.egulatory regions of a gene such as enhancers do not necessarily have to be close to the coding sequence on the linear molecule because the intervening DNA can be looped out to bring the gene and its regulatory region into proximity. Similarly, a gene's introns can be much larger than its exons.

Gene Expression Given this statistic, it is not surprising that the primary control point for gene expression is usually at the very beginning of the protein production process — the initiation of transcription. RNA transcription makes an efficient control point because many proteins can be made from a single mRNA molecule.t the same time, however, other amino acids would bind to negative regulatory proteins called repressors, which in turn bind to regulatory sites in the DNA that effectively block RNA polymerase binding (Figure 3). The control of gene expression in eukaryotes is more complex than that in prokaryotes.

An Introduction to Molecular Biology/Gene Expression Inhibition of protein translation is a major target for toxins and antibiotics, so they can kill a cell by overriding its normal gene expression control. Protein synthesis inhibitors include the antibiotic neomycin and the toxin ricin.

- Virtually all cells in the human body contain genes, making them potential targets for gene therapy. However, these cells can be divided into two major categories: somatic cells (most cells of the body) or cells of the germline (eggs or sperm).In theory it is possible to transform either somatic cells or germ cells.irtually all cells in the human body contain genes, making them potential targets for gene therapy.

The inactive form of the drug is called a pro drug.ene therapies to make cancer treatments work better. Some gene therapies put genes into cancer cells to make the cells more sensitive to particular treatments such as chemotherapy or radiotherapy. This type of gene therapy aims to make the other cancer treatments work better.

Gene expression Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product.These products are often proteins, but in non-protein coding genes such as transfer RNA (tRNA) or small nuclear RNA (snRNA) genes, the product is a functional RNA.xpression of a gene coding for a protein is only possible if the messenger RNA carrying the code survives long enough to be translated. In a typical cell, an RNA molecule is only stable if specifically protected from degradation.

Gene Gene. The term  gene  refers to a functional segment of DNA, which in eukaryotic cell s would be a part of a chromosome in the nucleus of the cell. Gene duplication occurs when an error in DNA replication leads to the duplication of a region of DNA containing a (generally functional) gene.ene therapy. From Wikipedia, the free encyclopedia. Gene therapy is the use of DNA as a pharmaceutical agent to treat disease. It derives its name from the idea that DNA can be used to supplement or alter genes within an individual's cells as a therapy to treat disease.

Gene silencing Gene silencing is a general term used to describe the regulation of gene expression. In particular, this term refers to the ability of a cell to prevent the expression of a certain gene. Gene silencing can occur during either transcription or translation and is often used in research.

What are gene families? A gene family is a group of genes that share important characteristics. In many cases, genes in a family share a similar sequence of DNA building blocks (nucleotides).These genes provide instructions for making products (such as proteins) that have a similar structure or function.ach grouping is given a name and symbol, and contains a table of the genes in that family. The Gene Ontology database lists the protein products of genes by their location within the cell (cellular component), biological process, and molecular function.
