Describe the process of 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.

Gene expression Measuring gene expression is an important part of many life sciences, as the ability to quantify the level at which a particular gene is expressed within a cell, tissue or organism can provide a lot of valuable information.

How do traits get expressed? Traits, which we define as visible aspects of an organism (known as the organism's phenotype) , are coded for by an organisms DNA and are expressed through the proteins that that DNA codes for. Here's the indepth version: Every living organism on this earth has DNA (or in some bacteria, RNA).

Terms Gene expression relates to which genes are transcribed and at what rates they are transcribed. Housekeeping genes are expressed at approximately equivalent levels in all cells. Inducible genes can be turned on or turned off, depending on the conditions in the cell and the cell type.

- Penetrance refers to whether the gene is expressed or not. That is, it refers to how many people with the gene have the trait associated with the gene. Penetrance is complete (100%) if everyone with the gene has the trait. Penetrance is incomplete if only some people with the gene have the trait. For example, 50% penetrance means that only half the people with the gene have the trait. Expressivity refers to how much the trait affects (or, is expressed in) a person. A trait may be very pronounced, barely noticeable, or in between.

Gene expression The process of gene expression is used by all known life-eukaryotes (including multicellular organisms), prokaryotes (bacteria and archaea), and utilized by viruses-to generate the macromolecular machinery for life.deally measurement of expression is done by detecting the final gene product (for many genes this is the protein) however it is often easier to detect one of the precursors, typically mRNA, and infer gene expression level.

Translations for gene expression 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 ribosomal RNA, transfer RNA or small nuclear RNA genes, the product is a functional RNA.n genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenotype. The genetic code stored in DNA is interpreted by gene expression, and the properties of the expression give rise to the organism's phenotype.

- 2.1 Genomic Imprinting. For some genes, only one copy is expressed. Expression of these genes is variable depending on which parent the gene came from, a process known as genomic imprinting.In this way, the active gene is preferentially transmitted from one parent over the other.or some genetic disorders, the expression of the phenotype is dependent on whether the mutation occurs in a gene that is imprinted. In other words, the phenotype depends on whether the mutated allele is inherited from the mother or the father.

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. Instead they must be turned into a gene product. Gene expression is the process by which the information contained within a gene becomes a useful product.

- A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene.

Gene expression The process of gene expression is used by all known life-eukaryotes (including multicellular organisms), prokaryotes (bacteria and archaea), and utilized by viruses-to generate the macromolecular machinery for life.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 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.n eukaryotes, transcription is performed by three types of RNA polymerases, each of which needs a special DNA sequence called the promoter and a set of DNA-binding proteins -- transcription factors —to initiate the process. RNA polymerase I is responsible for transcription of ribosomal RNA (rRNA) genes.

- Genomic imprinting is the epigenetic phenomenon by which certain genes are expressed in a parent-of-origin-specific manner. If the allele inherited from the father is imprinted, it is thereby silenced, and only the allele from the mother is expressed.

The variety of gene expression profiles characteristic of different cell types arise because these cells have distinct sets of transcription regulators.Some of these regulators work to increase transcription, whereas others prevent or suppress it.nly a fraction of the genes in a cell are expressed at any one time.

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.
