12 Difference Between Myelinated And Unmyelinated Nerve Fibers

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 12 Difference Between Myelinated And Unmyelinated Nerve Fibers

14 Difference Between Shigella And Salmonella

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. The genus is named after Kiyoshi Shiga, who first discovered it in 1897.

During infection, it typically causes dysentery. Shigellosis is a bacterial infection that affects … Read more 14 Difference Between Shigella And Salmonella

7 Difference Between Local And Global Sequence Alignment

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 7 Difference Between Local And Global Sequence Alignment

Fehling’s Test: Description, Reagent, Principle, Procedure & Result Interpretation

What Is Fehling’s Test? The Fehling’s test was developed by German chemist Hermann von Fehling in 1849. It is generally a test for reducing sugars and non-reducing sugars; and also a supplementary to the Tollens’ reagent test. The test can also be used to differentiate between water-soluble carbohydrate and ketone functional groups. Objectives of Fehling’s Test To detect the presence of carbohydrates in a solution. To … Read more Fehling’s Test: Description, Reagent, Principle, Procedure & Result Interpretation
