The key difference between symmetric and asymmetric stem cell division is that symmetric stem cell division produces two differentiated cells or two stem cells with equal cell fates while asymmetric stem cell division produces one stem and one non-stem daughter cell, which have different fates. Stem cells are undifferentiated cells that can proliferate indefinitely. They can differentiate into […]
Difference Between Operon and Cistron
The key difference between operon and cistron is that operon is a functional DNA unit present in prokaryotes and consists of several genes that are regulated by a single promoter and an operator while cistron is a term used to refer a gene, which is the functional unit of heredity that code for a protein. […]
Difference Between Artificial Selection and Genetic Engineering
The key difference between artificial selection and genetic engineering is that artificial selection selects already existing traits by breeding individuals that have desirable traits while genetic engineering modifies the genetic composition of plants or animals by introducing genes of new traits or silencing genes. Genetic engineering is a novel field in Biotechnology. It allows the […]
Difference Between Direct and Indirect Hormone Action
The key difference between direct and indirect hormone action is that direct hormone action occurs when hormones directly act on non-endocrine tissues while indirect hormone action occurs when hormones modulate the secretory activity of other glands. Hormones are chemical messenger secreted into the bloodstream. They can be amino acid derivatives, peptide hormones or lipid derivatives. […]
Difference Between Ribitol and Glycerol Teichoic Acid
The key difference between ribitol and glycerol teichoic acid is that ribitol teichoic acid contains polyribitol phosphate units in the main chain, while glycerol teichoic acid contains poly-glycerol phosphate units in the main chain. Teichoic acid is a compound found in the cell wall of most Gram-positive bacteria. Teichoic acids are copolymers of glycerol phosphate […]
Difference Between Regeneration and Fibrosis
The key difference between regeneration and fibrosis is that regeneration involves replacing injured cells with cells of the same type while fibrosis involves replacing parenchyma tissue with connective tissues, leading to the formation of permanent scar tissue. Repairing of the damaged tissue is a fundamental biological process. This process replaces dead and damaged cells orderly, […]
Difference Between Culture and Media in Microbiology
The key difference between culture and media in microbiology is that culture in microbiology is a method of growing and maintaining microorganisms in vitro for different analysis while media in microbiology are solid or liquid formulations which contain nutrients and other necessary materials to support the growth of microorganisms and cells. Microorganisms are tiny organisms […]
Difference Between Filgrastim and Lenograstim
The key difference between filgrastim and lenograstim is that filgrastim is a recombinant methionyl human G CSF which is expressed by E. coli while lenograstim is a glycosylated recombinant human G CSF which is expressed by Chinese hamster ovarian cell lines. Granulocyte colony-stimulating factor (G CSF) is a protein secreted by many cells such as endothelial cells, monocytes and fibroblasts […]
Difference Between Parallel and Antiparallel Beta Pleated Sheets
The key difference between parallel and antiparallel beta pleated sheets is that in parallel beta pleated sheets, polypeptide strands run in the same direction, while in antiparallel beta pleated sheets, neighbouring strands run in opposite directions. Beta pleated sheet or beta sheet is a common secondary structure of proteins. There are hydrogen bonds between beta […]
Difference Between Trypanosoma Cruzi and Trypanosoma Rangeli
The key difference between Trypanosoma cruzi and Trypanosoma rangeli is that Trypanosoma cruzi is pathogenic to humans while Trypanosoma rangeli is harmless to humans. Protozoa is a major group of Kingdom Protista. This group includes animal-like single-cell eukaryotic organisms. Trypanosoma is a genus of protozoa that contains about 20 species. Among the 20 species, T. […]
