The key difference between ortho, para and meta substitution is that ortho substitution has two substituents in 1 and 2 positions of the ring, but para substitution has two substituents in 1 and 4 positions. Meanwhile, meta substitution has two substituents in 1 and 3 positions. The terms ortho para and meta refer to different […]
Difference Between Phenylalanine and Tyrosine
The key difference between phenylalanine and tyrosine is that phenylalanine is an essential amino acid which cannot be made in our body and must be included into the diet while tyrosine is a nonessential amino acid which can be formed from the phenylalanine in our body. There are twenty different amino acids. Some amino acids […]
Difference Between Photochromic and Thermochromic
The key difference between photochromic and thermochromic is that photochromic materials darken upon exposure to UV radiation, whereas thermochromic materials change their colour upon changes in temperature. The terms photochromic and thermochromic are mainly used in the context of lenses where the colours change due to changes in some factors like frequency of light and […]
Difference Between Candidate Gene and GWAS
The key difference between candidate gene and GWAS is that candidate gene approach investigates the genetic variation within a small number of pre-specified genes of interest while GWAS investigates the entire genome for a common genetic variation behind a particular disease condition. Candidate gene approach and genome-wide association studies (GWAS) are two methods that are […]
Difference Between V Type and F Type ATPase
The key difference between V type and F type ATPase is that V type ATPase works as an ATP-driven ion pump while F type ATPase functions as ATP synthase in cells. ATPase is a term that refers to enzymes that are able to hydrolyze ATP. Generally, ATPases decompose ATP and the energy released during the […]
Difference Between PP and PET
The key difference between PP and PET is that PP is a saturated polymer, whereas PET is an unsaturated polymer. The term PP stands for polypropylene while PET stands for polyethylene terephthalate. These are polymer materials made of many monomers. The monomer used to produce the polymer material is shown as the repeating unit of […]
Difference Between Symplast and Vacuolar Pathway
The key difference between symplast and vacuolar pathway is that in the symplast pathway, water does not enter into vacuoles while in the vacuolar pathway, water passes into vacuoles. Water moves through plant cells, especially across the root, via three major pathways. They are apoplast, symplast and vacuolar pathways. In the apoplast pathway, water and […]
Difference Between Branched and Crosslinked Polymers
The key difference between branched and crosslinked polymers is that branched polymer molecules have side chains that are attached to the backbone of the polymer, whereas crosslinked polymer materials have linkages between major polymer molecules. Polymers are macromolecules containing a high number of repeating units. These repeating units represent the monomers that were used to […]
Difference Between Centromere and Chromomere
The key difference between centromere and chromomere is that centromere is a constricted region that joins sister chromatids together in a chromosome while chromomere is a linearly arranged bead-like structure present along the length of the chromosome. A chromosome is a threadlike structure composed of nucleic acids and proteins. They contain the genetic information of […]
Difference Between Ion Exchange and Reverse Osmosis
The key difference between ion exchange and reverse osmosis is that ion exchange is a physio-chemical method that selectively removes contaminants by effectively exchanging ions of similar electrical charges while reverse osmosis is a physical method in which water is passed across a semi-permeable membrane against a concentration gradient, applying a pressure. Water purification is […]
