Also called an antibacterial. A type of antimicrobial drug used in the treatment and prevention of bacterial infections. Archaea One of the three recognized domains of organisms, the other two being Bacteria and Eukaryota. artificial selection Also called selective breeding. The process by which humans use animal breeding and plant breeding to selectively control the development of particular ...
Robotic preparation of MALDI mass spectrometry samples on a sample carrier. Proteomics is the large-scale study of proteins. [1] [2] Proteins are vital macromolecules of all living organisms, with many functions such as the formation of structural fibers of muscle tissue, enzymatic digestion of food, or synthesis and replication of DNA.
The proteome is the entire complement of proteins, including the modifications made to a particular set of proteins, produced by an organism or system. Proteomics: Large-scale study of proteins, particularly their structures and functions. Mass spectrometry techniques are used.
A fibrous network of proteins lining the inner, nucleoplasmic surface of the nuclear envelope, composed of filaments similar to those that make up the cytoskeleton. It may function as a scaffold for the various contents of the nucleus including nuclear proteins and chromosomes. [3] nuclear localization signal (NLS) Also nuclear localization ...
The loss of these interactions alters the proteins structure, but most importantly it alters the proteins function, which can be beneficial or detrimental. A significant change in pH may even disrupt many interactions the amino acids make and denature (unfold) the protein. [24]
Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the ...

The cry proteins were discovered to provide the insecticidal activity in 1956, and by the 1980s, scientists had successfully cloned the gene that encodes this protein and expressed it in plants. [15] The gene that provides resistance to the herbicide glyphosate was found after seven years of searching in bacteria living in the outflow pipe of a ...
