G protein-coupled receptors (GPCRs) are a large family of membrane proteins that play a critical role in cellular signaling. These receptors are characterized by their ability to pass through the cell membrane seven times (hence they are also known as seven-transmembrane receptors). GPCRs respond to a variety of external signals, including hormones, neurotransmitters, and environmental stimuli, and are involved in many physiological processes.

As of my last knowledge update in October 2021, I do not have specific information regarding a company called "Gartons Limited." It is possible that it is a smaller or less widely-known company that operates in a particular industry, or it may have emerged after my last update.

Gaseous signaling molecules are small, diffusible molecules that can easily cross cellular membranes and play a crucial role in various biological processes. These molecules typically exist in a gaseous state at physiological temperatures and pressures and can function as signaling messengers in a variety of physiological and pathological contexts.

Gateway technology generally refers to systems or devices that facilitate communication and data transfer between different networks or protocols. This can include hardware devices as well as software platforms that act as intermediaries to enable interoperability, allowing different systems to communicate seamlessly. Here are some contexts in which gateway technology is commonly used: 1. **Network Gateways**: These are devices that connect two different networks, often with different protocols. They can translate communication protocols, allowing data to flow from one network type to another (e.g.

Gel electrophoresis is a laboratory technique used to separate and analyze macromolecules such as DNA, RNA, and proteins based on their size and charge. The basic process involves the following key components and steps: 1. **Gel Matrix**: A gel, commonly made from agarose or polyacrylamide, serves as a medium through which the molecules will travel. The pore size of the gel can be adjusted by varying its concentration, allowing for separation of different sizes of molecules.

Gel electrophoresis of nucleic acids is a laboratory technique used to separate and analyze DNA or RNA fragments based on their size and charge. This method utilizes an electric field to move nucleic acids through a gel matrix, typically composed of agarose or polyacrylamide, which acts as a sieve.

Gel electrophoresis of proteins is a laboratory technique used to separate and analyze proteins based on their size, charge, and other physical properties. It involves the movement of charged molecules through a gel matrix under the influence of an electric field. Here are the key components and steps involved in the process: ### Key Components: 1. **Gel Matrix**: Typically made from agarose or polyacrylamide, the gel serves as a medium through which proteins can migrate.

Gel extraction is a molecular biology technique used to purify DNA or RNA fragments from an agarose gel after electrophoresis. This process is essential when researchers need to isolate specific nucleic acid fragments for further analysis, cloning, or other applications. The general steps involved in gel extraction are as follows: 1. **Electrophoresis**: Nucleic acids are separated by size using gel electrophoresis. The gel is typically made from agarose and contains wells where the samples are loaded.

GenGIS is a software application designed for the visualization and analysis of genomic data in the context of geographic information systems (GIS). It allows researchers to map genomic data onto geographic landscapes, enabling the exploration of spatial patterns and relationships in biological data. GenGIS can be particularly useful in fields such as ecology, evolutionary biology, and epidemiology, where understanding the spatial distribution of genetic variation is important.

A gene is a fundamental unit of heredity in living organisms. It is a segment of DNA (deoxyribonucleic acid) that contains the instructions necessary for the synthesis of proteins, which perform a wide range of functions in the body, including structural, regulatory, and enzymatic roles. Genes are organized along chromosomes, which are structures found in the nucleus of cells. Each gene has a specific location, known as a locus, on a chromosome and can vary in size.

GeneRIF (Gene Reference Into Function) is a database and resource that provides concise functional descriptions or annotations for specific genes. It is part of the National Center for Biotechnology Information (NCBI) resources and includes brief summaries about the biological roles, characteristics, and significance of genes based on published research.

GeneXpert Infinity is a diagnostic testing platform developed by Cepheid that is used for rapid molecular testing. It is part of the GeneXpert system, which is known for its ability to perform real-time PCR (polymerase chain reaction) testing. The platform is designed to provide quick and accurate results for a variety of infectious diseases, including tuberculosis, respiratory infections, and sexually transmitted infections, among others.

Gene expression is the biological process through which the information encoded in a gene is used to produce a functional gene product, usually a protein, but it can also refer to the production of non-coding RNA molecules such as rRNA, tRNA, or microRNA. This process involves several key steps: 1. **Transcription**: The DNA sequence of a gene is transcribed into messenger RNA (mRNA) by RNA polymerase.

A gene gun, also known as a biolistic particle delivery system, is a device used to deliver DNA or other genetic material into cells. This technique is commonly employed in biotechnology and genetic engineering, particularly for plants and some animal cells. The gene gun works by accelerating tiny particles, often made of gold or tungsten, that are coated with the DNA of interest.

Gene knock-in is a genetic engineering technique used to introduce a specific gene or a modified version of a gene into a particular location in the genome of an organism. This method allows researchers to study the effects of that gene on biological processes, disease mechanisms, or to develop models for human diseases.

Gene nomenclature refers to the system of naming genes to provide a standardized framework that allows for the consistent identification and classification of genes across different species and studies. This is important because it facilitates communication among researchers, ensures clarity in scientific literature, and helps avoid confusion that can arise from synonyms, orthologs, or different naming conventions.

Gene targeting is a molecular biology technique used to create specific modifications in the genome of an organism. It allows researchers to alter, delete, or insert genes at precise locations in the DNA sequence. This method is particularly valuable in functional genomics and gene therapy, as it enables the study of gene function and the modeling of genetic diseases.

Gene therapy is a medical technique that involves altering the genes inside a patient's cells to treat or prevent disease. The goal of gene therapy is to correct or replace faulty genes that are responsible for disease development or progression. There are several approaches to gene therapy, including: 1. **Gene Replacement**: Introducing a normal copy of a gene to replace a mutated or nonfunctional gene.

Gene therapy for the human retina is a medical treatment that aims to address inherited retinal diseases through the introduction, removal, or alteration of genetic material within the retinal cells. The primary goal is to correct or compensate for defective genes that lead to vision loss or retinal degeneration.

The genetic code is a set of rules that defines how the information encoded in DNA or RNA sequences is translated into proteins, which are essential for the structure and function of living organisms. It is essentially the language of genetic information. Here are some key points about the genetic code: 1. **Codons**: The genetic code consists of sequences of three nucleotides, known as codons. Each codon corresponds to a specific amino acid or a stop signal during protein synthesis.
