Induced Fit Theory Essay Example
642 words 3 pages

Induced fit theory is a variation of the lock-and-key theory of enzymatic function. It is proposed that the substrate causes a conformational change in the enzyme such that the active site achieves the exact configuration required for a reaction to occur. The overall effect would be a tighter binding for the substrate and enzyme. Think […]

Oligomycin: The Killer Antibody Essay Example
1041 words 4 pages

Discovered in 1953, Oligomycin is a deadly antibody produced by the gram-positive streptomyce bacterial clan. It stops oxidative phosphorylation within mitochondria, ultimately leading to human death. The movement of protons is stopped by the Oligomycin complex through altering the active sites and proton-bearing sites of the polypeptide chain. This modification creates non-covalent, irreversible, polar, and […]

Popular Questions About Molecular Biology

What are basic molecular biology techniques?
One of the most basic techniques of molecular biology to study protein function is molecular cloning. In this technique, DNA coding for a protein of interest is cloned using polymerase chain reaction (PCR), and/or restriction enzymes into a plasmid (expression vector).
What are the principles of molecular biology?
Gel electrophoresis is one of the principal tools of molecular biology. The basic principle is that DNA, RNA, and proteins can all be separated by means of an electric field and size.
What is an example of molecular biology?
Molecular biology is the study of life at the level of atoms and molecules. Suppose, for example, that one wishes to understand as much as possible about an earthworm. At one level, it is possible to describe the obvious characteristics of the worm, including its size, shape, color, weight, the foods it eats, and the way it reproduces.
What is the central principle of molecular biology?
The central dogma of molecular biology is an explanation of the flow of genetic information within a biological system. It is often stated as "DNA makes RNA and RNA makes protein," although this is not its original meaning.
