The key difference between villi and alveoli is that villi are the finger-like projections present on the inner lining of the small intestine and facilitate nutrient absorption while alveoli are the tiny sac-like structures present in the lung that facilitate rapid exchange of oxygen and carbon dioxide. Villi and alveoli are two important structures present in […]
Difference Between Hyaloplasm and Cytosol
The key difference between hyaloplasm and cytosol is the absence and presence of cell organelles. Hyaloplasm comprises of structureless fluid while cytosol comprises of fluid and structured organelles. Hyaloplasm and cytosol are organic fluid substances found in a cell. They can be observed in prokaryotic cells as well are eukaryotic cells. The hyaloplasm refers to […]
Difference Between Endosymbiosis and Invagination
The key difference between endosymbiosis and invagination is that endosymbiosis is a theory that explains the origin of mitochondria and chloroplasts inside the eukaryotic cell while the invagination is a process that explains the origin of the nucleus and other cell organelles through the formation of invagination from the plasma membrane to the cell interior. […]
Difference Between Lamellipodia and Filopodia
The key difference between lamellipodia and filopodia is that the lamellipodia are cytoskeletal actin projections present in the mobile edges of the cells while filopodia are thin cytoplasmic protrusions that extend from the leading edge of the mobile cells. Lamellipodia and filopodia are two cellular extensions commonly used in cell probing and migration. These structures […]
Difference Between DNA Sequence Mutations and Epigenetic Modifications
The key difference between DNA sequence mutations and epigenetic modifications is that during DNA sequence mutations, changes occur in the original DNA sequences while during epigenetic modifications, changes do not occur in the original DNA sequences. The genome represents the overall genetic information of an organism in the form of precise DNA sequences or genes. […]
Difference Between lincRNA and lncRNA
The key difference between lincRNA and lncRNA is the length of the RNA. That is; the lincRNAs are long strands of RNA whereas lncRNAs are comparatively short strands of RNA. RNA or Ribonucleic acid is an important biomolecule which has varied functions. There are many new discoveries taking place in terms of RNA. lincRNA and […]
Difference Between Chemotaxis and Phagocytosis
The key difference between chemotaxis and phagocytosis is that the chemotaxis is a directed migration of cells or an organism along a chemical concentration gradient while phagocytosis is a mechanism that engulfs foreign infectious particles in order to neutralize or destroy them. Leukocytes are important cells of the immune system. They are white blood cells. […]
Difference Between Fetal and Embryonic Stem Cells
The key difference between fetal and embryonic stem cells is that fetal stem cells are comparatively more differentiated whilst embryonic stem cells are less differentiated. Stem cells are a type of cells with the potential to be differentiated into many forms of cells. They also possess the ability to self renew and produce the same […]
Difference Between Ribozymes and Protein Enzymes
The key difference between ribozymes and protein enzymes is that the ribozymes are RNA molecules that are capable of catalyzing certain specific biochemical reactions while the protein enzymes are protein molecules that are capable of catalyzing most of the biochemical reactions occurring in the living organisms. Enzymes are biological catalysts, and they speed up the […]
Difference Between Biotin and Keratin
The key difference between biotin and keratin is that biotin is a water-soluble vitamin while keratin is a structural protein. Biotin and keratin are essential components of the body that carry out many important functions. Unlike biotin, keratin is extremely water insoluble. Biotin takes part in metabolic activities while keratin functions as a protective protein. […]
