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. […]
Difference Between Phytomastigophora and Zoomastigophora
The key difference between Phytomastigophora and Zoomastigophora is that the members of Phytomastigophora contain chloroplasts in their cytoplasm while the members of Zoomastigophora do not contain chloroplast in their cytoplasm. Mastigophora is a subphylum of Kingdom Protista. They are single-celled eukaryotes which are protozoans. They may form colonies or exist as single cells and can […]
Difference Between Chlamydomonas and Spirogyra
The key difference between Chlamydomonas and spirogyra is that Chlamydomonas is a single-celled spherical-shaped green alga which is highly motile while spirogyra is a multicellular filamentous green alga which has spirally arranged chloroplasts. Green alga is a group of algae belonging to Kingdom Protista. Similar to land plants, they have a cellulose cell wall, […]
Difference Between Conditional and Constitutive Knockout
The key difference between conditional and constitutive knockout is that conditional knockout is the deletion of a gene of interest from a specific tissue or organ while constitutive knockout is the permanent deletion of a gene of interest from the animal. Mouse is a good analogue for most human biological processes since they share about […]
Difference Between Inducible and Constitutive Promoter
The key difference between inducible and constitutive promoter is that the inducible promoter is a regulated promoter that is active only in response to specific stimuli while the constitutive promoter is an unregulated promoter which is active in all circumstances. Promoter is an essential part of a gene. It is a DNA sequence located near […]
Difference Between Cachexia and Sarcopenia
The key difference between cachexia and sarcopenia is that cachexia is defined as weight loss due to an underlying illness, while sarcopenia is defined as the loss of muscle mass and function associated with ageing. Cachexia and sarcopenia are muscle wasting disorders that mainly affect cancer patients and the ageing population, respectively. Sarcopenia is the […]
Difference Between Random Orientation and Independent Assortment
The key difference between random orientation and independent assortment is that random orientation is the random line up of homologous chromosome pairs at the equator during the metaphase of meiosis 1 while independent assortment refers to the inheritance of genes independently from the inheritance of any other gene. Cell divisions make new vegetative cells or […]
Difference Between Leeches and Bloodsuckers
The key difference between leeches and bloodsuckers is that leeches are soft, segmented, parasitic or predatory worms that feed by sucking blood from other animals while bloodsuckers are animals that show blood-feeding behaviour. Blood is a good source of nutrients. It is also highly available. Certain animals, including parasites, feed on blood. They live on […]
