- (November 2008) An accession number in bioinformatics is a unique identifier given to a DNA or protein sequence record to allow for tracking of different versions of that sequence record and the associated sequence over time in a single data repository.

Key (cryptography) From Wikipedia, the free encyclopedia. In cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm. For encryption algorithms, a key specifies the transformation of plaintext into ciphertext, and vice versa for decryption algorithms.

9. Primary Key DEFINITION: A primary key is a field in a table which is unique and enables you to identify every record in that table. Imagine what would happen if Mrs Smith telephoned the school to ask the secretary to pass on a message to her daughter Charlotte.

Why Is a Primary Key Important? In database design, a primary key is important because it serves as a unique identifier for a row of data in a database table. A primary key makes it convenient for a user to add, sort, modify or delete data in a database. Continue Reading.

- Key Concepts: Biological control is use of material of biological origin to control the numbers or effects of a target organism. Biological control includes the use of predators, competitors, pathogens and compounds of biological origin. Microorganisms used include viruses, bacteria, fungi and protozoans.These may cause disease, or may compete with or otherwise limit the target organism. Biological controls tend to be highly specific.iological control includes the use of predators, competitors, pathogens and compounds of biological origin.

Whatâs the purpose / use of primary and foreign keys? Primary and foreign keys are a way in which to constrain related data together to ensure data in your database remains consistent and to ensure no redundant data is in the database as a result of deleting a table or row in one table that affects data in other tables that may perhaps rely on that information.

What Is a Taxonomic Key? Also called a  dichotomous key, a taxonomic key gives users a systematic and reproducible way to identify items and organisms. It is used for a variety of purposes, such as identifying unknown organisms to a certain taxonomic level (e.g. family, genus and species) and identifying rocks or minerals.

Biopharmaceutical When a new biopharmaceutical is developed, the company will typically apply for a patent, which is a grant for exclusive manufacturing rights. This is the primary means by which the developer of the drug can recover the investment cost for development of the biopharmaceutical.n the European Union, a biological medicinal product is one of the active substance(s) produced from or extracted from a biological (living) system, and requires, in addition to physico-chemical testing, biological testing for full characterisation.

Biological Assays A bioassay or biological assay is a biological testing procedure for estimating the concentration of a pharmaceutically active substance in a formulated product or bulk material. In contrast to common physical or chemical methods, a bioassay results in detailed information on the biological activity of a substance. bioassay or biological assay is a biological testing procedure for estimating the concentration of a pharmaceutically active substance in a formulated product or bulk material.

biometrics (n.) Biometrics generally refers to the study of measurable biological characteristics. In computer security, biometrics refers to authentication techniques that rely on measurable physical characteristics that can be automatically checked. There are several types of biometric identification schemes: 1  face: the analysis of facial characteristics. 2  fingerprint: the analysis of an individual's unique fingerprints.  hand geometry: the analysis of the shape of the hand and the length of the fingers.

- Biological nomenclature is a language that we use to communicate ideas and information about the diversity of life. It is an information retrieval system conveying information about diversity and relationships.Common names for species are words in the language of the layperson.omenclature is not an end to systematics and taxonomy but is a necessity in organizing information about biodiversity. Nomenclature functions to provide labels (names) for all taxa at all levels in the hierarchy of life.

The world's most secure front door The biometric lock is very clever, ensuring that it can sense bloodflow in a finger before it unlocks the door – when first generation fingerprint locks were first used in Colombia, they were circumvented by unscrupulous assailants who would hack off the victim’s finger for use in their fingerprint reader.

- The international biohazard symbol. Biological hazards, also known as biohazards, refer to biological substances that pose a threat to the health of living organisms, primarily that of humans. This can include medical waste or samples of a microorganism, virus or toxin (from a biological source) that can affect human health.

- Function (biology) From Wikipedia, the free encyclopedia. A biological function is the reason some object or process occurred in a system that evolved through a process of selection or natural selection. Thus, function refers forward from the object or process, along some chain of causation, to the goal or success.

What Is Biological Psychology? What Is Biological Psychology? Biological psychology, or biopsychology, is a field in which the mind-body connection is explored through scientific research and clinical practice. Researchers in this field study the biological basis of thoughts, emotions and behaviors. Read on to learn more about this subfield of psychology, educational options and potential careers.

Biological engineering Biological engineering is a science-based discipline founded upon the biological sciences in the same way that chemical engineering, electrical engineering, and mechanical engineering can be based upon chemistry, electricity and magnetism, and classical mechanics, respectively.iological engineering can be differentiated from its roots of pure biology or other engineering fields. Biological studies often follow a reductionist approach in viewing a system on its smallest possible scale which naturally leads toward the development of tools like functional genomics.

Biomarker A biomarker, or biological marker, generally refers to a measurable indicator of some biological state or condition. The term is also occasionally used to refer to a substance the presence of which indicates the existence of a living organism.n genetics, a biomarker (identified as genetic marker) is a DNA sequence that causes disease or is associated with susceptibility to disease. They can be used to create genetic maps of whatever organism is being studied.

Biological detergent A biological detergent is a laundry detergent that contains enzymes harvested from micro-organisms such as bacteria adapted to live in hot springs.The description is commonly used in the United Kingdom, where other washing detergents are described as non-biological (or bio and non-bio).iological detergents clean in the same way as non-biological ones with additional effects from the enzymes, whose purpose is to break down protein, starches and fat in dirt and stains on clothing to be laundered, for example food stains, sweat and mud.
