What Is SN1 Reaction? The SN1 reaction is a substitution reaction in organic chemistry. ‘’SN’’ stand for ‘’nucleophilic substitution’’ and ‘’1’’ says that the rate-determining step is unimolecular. Thus, the rate equation is often shown as having first-order dependence on electrophile and zero-order dependence on nucleophile. This relationship holds for situations where the amount of … Read more
DNA is a two-stranded molecule. One strand of DNA holds the information that codes for various genes, this often referred to as the template strand or antisense strand (containing anticodons).

Concentration refers to how much a particular object or particle is in a given space. Gasses and molecules in a liquid have a tendency to diffuse from a … Read more
What Is Cofactor? A cofactor is a non-protein chemical compound that is required for the protein’s biological activity. Many enzymes require cofactors to function properly. Cofactors can be considered “helper molecules’’ that assist enzymes in their action. Many cofactors will sit in the enzyme site and assist the biding of the substrate. An inactive enzyme … Read more
What Are Stack Data Structure? Stack is an abstract data type that serves as a collection of elements, with two principal operations: PUSH, which adds an element to the collection and POP which removes the most recently added element that was not yet removed. Generally, stacks are based on Last In First Out (LIFO) principle … Read more
