What is Parenchyma? Parenchyma is a plant, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion food storage, and other activities of plant life. Parenchyma cells can serve many functions. … Read more

Neurons are specialized cells that transmit chemical and electrical signals in the brain; they are the basic building blocks of the central nervous system. The primary components of the neuron are the soma (cell body), the axon (a long slender projection that conducts electrical impulses away from the cell body), dendrites (tree-like structures that receive … Read more

Shigella Shigella is a genus of bacteria that is Gram-negative, facultative anaerobic, non-spore-forming, nonmotile, rod-shaped and genetically closely related to E. coli.

During infection, it typically causes dysentery. Shigellosis is a bacterial infection that affects … Read more

Local And Global Sequence Alignment A sequence alignment is a way of arranging the sequences of DNA, RNA, or protein to identify regions of similarity that may be a consequence of functional, structural, or evolutionary relationships between the sequences. Aligned sequences of nucleotide or amino acid residues are typically represented as rows within a matrix. Gaps are inserted between the residues so that identical or similar characters are aligned in … Read more

Overview Hybridization (also spelled hybridisation) refers to the process of producing offspring by mating two parents from different varieties or species. It is sometimes used synonymously with crossbreeding, which is defined as the process or the act of producing offspring particularly through mating two purebred individuals but come from different breeds or varieties, (sometimes, even species). … Read more
