The key difference between temporary and permanent hardness of water is that temporary hardness of water can be removed by boiling the water, whereas permanent hardness cannot be removed by boiling. We can define water hardness as the measurement of the concentration of total divalent ions present in water. Examples of some divalent ions present […]

Difference Between Electroporation and Microinjection
The key difference between electroporation and microinjection is that electroporation is a technique that uses a high voltage electric pulse to deliver DNA into host cells while microinjection is a technique that uses a fine-tipped glass needle or micropipette to deliver DNA into host cells. Transformation is the process by which foreign DNA is transferred […]
Difference Between Metal Excess Defect and Metal Deficiency Defect
The key difference between metal excess defect and metal deficiency defect is that metal excess defect is caused by anionic vacancies and extra cations in the interstitial sites whereas metal deficiency defect is caused by cationic vacancies and extra anions in the interstitial sites. Metal excess defect and metal deficiency defect are two types of […]
Difference Between pre-mRNA and mRNA
The key difference between pre-mRNA and mRNA is that pre-mRNA is the first product of the transcribed gene and contains both non-coding sequences (introns) and coding sequences (exons) while mRNA is the second product of a transcribed gene which contains only coding sequences. Gene is the functional unit of heredity. It is a specific DNA […]
Difference Between Ionic Covalent and Metallic Hydrides
The key difference between ionic covalent and metallic hydrides is their formation. Ionic hydrides form when hydrogen reacts with highly electropositive s-block elements; covalent hydrides form when atoms of chemical elements having comparable electronegativity values react with hydrogen whereas metallic hydrides form when transition metals react with hydrogen. A hydride is a chemical compound having […]
Difference Between Gallium and Mercury
The key difference between gallium and mercury is that gallium has a very low density compared to mercury. Gallium and mercury are unique chemical elements that occur in the liquid state at near room temperature. It’s important to note that mercury is essentially a liquid at room temperature while gallium becomes liquid at temperatures near […]
Difference Between Symmetric and Asymmetric Stem Cell Division
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 TDS and Salinity
The key difference between TDS and salinity is that TDS is the measurement of all types of solid compounds in a given liquid sample whereas salinity is the measurement of the amount of salt that is dissolved in a given liquid sample. Often, people use the terms TDS and salinity interchangeably though they are two […]
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 […]
