The key difference between helix-loop-helix and helix-turn-helix is that helix-loop-helix mediates protein dimerization while helix-turn-helix regulates gene expression through DNA binding. A protein motif is a short-conserved sequence associated with distinct functions of DNA. It is mainly associated with a special structural site with a unique chemical or biological function. These motifs contain small regions […]
What is the Difference Between Eutectoid Reaction and Peritectic Reaction
The key difference between eutectoid reaction and peritectic reaction is that eutectoid reaction is the conversion of one solid phase into two other solid phases, whereas peritectic reaction is the conversion of a liquid phase and a solid phase into a different solid phase. A eutectoid reaction is a chemical reaction in which a solid […]
What is the Difference Between pH Meter and Conductivity Meter
The key difference between pH meter and conductivity meter is that the pH meter measures the activity of hydrogen ions in aqueous solutions, whereas the conductivity meter measures voltage through the comparison of an unknown voltage with a known voltage. A pH meter can be described as a type of potentiometer we can use to […]
What is the Difference Between Dettol and Phenol
The key difference between Dettol and phenol is that Dettol is an antiseptic and disinfectant we can apply on wounds, whereas phenol is a corrosive substance that is not suitable for applications on humans. Dettol is a brand name for a type of antiseptic substance introduced by Reckitt (a British company). Phenol is an organic […]
What is the Difference Between Urea and Potassium Sulphate
The key difference between urea and potassium sulphate is their importance as a fertilizer. Urea is important in providing plants with nitrogen, which can promote green leafy growth, whereas potassium sulfate is important in providing plants with potassium and sulfur chemical species. Urea can be described as an organic compound having the chemical formula CO(NH2)2, […]
What is the Difference Between Formalin and Paraformaldehyde
The key difference between formalin and paraformaldehyde is that formalin is a solution consisting of paraformaldehyde units, whereas paraformaldehyde is a type of polymer formed from formaldehyde. Formalin is a colorless solution of formaldehyde in the water, while paraformaldehyde is a polymer compound that can be categorized as a poly-acetal. CONTENTS 1. Overview and Key Difference […]
What is the Difference Between Positive and Negative Supercoiling of DNA
The key difference between positive and negative supercoiling of DNA is that during positive supercoiling of DNA, the DNA strand is overwound compared to the relaxed state, while during negative supercoiling of DNA, the DNA strand is under wound compared to the relaxed state. DNA supercoiling is the amount of twist in a DNA strand […]
What is the Difference Between PTH and TSH
The key difference between PTH and TSH is that PTH is a peptide hormone secreted by the parathyroid gland that regulates serum calcium ion concentration through its effect on bone, kidneys, and intestine, while TSH is a peptide hormone secreted by the pituitary gland, which stimulates the thyroid gland to produce thyroxine and triiodothyronine in […]
What is the Difference Between Heavy Chain and Light Chain
The key difference between heavy chain and light chain is that heavy chain is the large polypeptide subunit of an antibody, while light chain is the small polypeptide subunit of an antibody. An antibody is an immunoglobulin. It is a large Y-shaped protein used by the immune system to identify and neutralize foreign proteins such […]
What is the Difference Between Formality and Molarity
The key difference between formality and molarity is that formality does not consider what happens to the substance after it is dissolved in a solvent when calculating the value, whereas molarity takes into account what happens to the solute once it is dissolved when taking the measurement. Formality is the total concentration of a substance […]
