What is Nervous System? Definition of Nervous System The nervous system is a complex network of cells and tissues that coordinates and regulates the activities of an organism by transmitting electrical signals between different parts of the body. Cells of the Nervous System Neurones Glial Cells Astrocytes Oligodendrocytes Microglia Ependymal cells Nervous System Structure and … Read more
What is Recombinant DNA Technology? Definitions of Recombinant DNA Technology Recombinant DNA technology is a method used to manipulate and combine DNA from different sources to create new genetic combinations. It involves inserting genes from one organism into the DNA of another, allowing for the production of specific proteins or traits not naturally found in … Read more
The early detection of diseases is crucial for effective treatment, and molecular diagnostics serves as a pivotal tool in this regard. This term encompasses a range of diagnostic techniques that assess an individual’s health at a molecular level. Specifically, molecular diagnostics focuses on the identification and quantification of genetic sequences—often referred to as biomarkers—found in … Read more
Animal cells are ideal for recombinant protein production because they possess the ability to carry out post-translational modifications, a process that is often lacking in bacterial cells. This capability makes animal cells essential for the commercial synthesis of various biological products, including antibodies, hormones, growth factors, cytokines, and viral coat proteins, which are used in … Read more
Tissue Culture is the term used to describe the process of removing tissues, cells or organs from either a plant or animal and their subsequent transfer into an artificial environment that encourages development.
What is Transgenic Animal? Definition of Transgenic Animal A transgenic animal is an organism that has had a foreign gene (transgene) deliberately inserted into its genome, allowing the gene to be expressed and passed on to future generations. Steps for Production of Transgenic Animals The production of transgenic animals involves a detailed and systematic approach … Read more
What are Biosensors? Definition of Biosensors A biosensor is a device that detects biological changes and converts them into an electrical signal, typically by combining a biological sensing element with a transducer for applications like medical diagnostics or environmental monitoring. Components of Biosensors Biosensors consist of several key components that work together to detect biological … Read more
What is High Throughput Sequencing (HTS)? Working Principle of High Throughput Sequencing (HTS) High-throughput sequencing (HTS) technologies High-throughput sequencing (HTS) technologies have revolutionized genomic research by enabling rapid and detailed analysis of genetic material. The principal HTS technologies can be categorized into next-generation sequencing (NGS) and third-generation sequencing. Each of these technologies has distinct methodologies, … Read more
Proteins are fundamental to virtually all biological processes, serving as the building blocks of cells, enzymes catalyzing biochemical reactions, and key regulators of cellular functions. Understanding protein structures, functions, and interactions is essential for advancing biological research, drug development, and medical diagnostics. The sheer complexity and diversity of proteins, however, pose significant challenges for researchers … Read more
The DNA Data Bank of Japan (DDBJ) is a pivotal resource in the realm of genomics and bioinformatics, playing a crucial role in advancing scientific research and collaboration. Established in 1987, DDBJ was created to support the growing need for accessible, comprehensive genomic data. Its mission is to collect, maintain, and disseminate DNA sequence data, … Read more
