The word molecule comes from the Latinmoleculameaning a unit of mass. This name was to encompass its original meaning of "the smallest unit of a substance that still retains the properties of that substance." In 1873, James Maxwell defined atom and molecule: "An atom is a body which cannot...
Restriction fragment length polymorphisms are marker molecules that are used to follow a particular DNA sequence as it passes between cells. It is one of the most common types of molecular markers and is based on the hybridization of cloned DNA to DNA fragments. They are specific to a single ...

What is the molecule rRNA a component of?RNA FirstMany scientists think that the first form of information that early pre-cells had was in the form of RNA, not DNA. This is because RNA can not only be used to share information, it can also act as a catalyst for chemical reactions. ...
Atoms are the building blocks of matter. A combination of atoms forms amolecule. Large groups of atoms and molecules form the bulk matter of day-to-day life in the physical world. There are more than 100 different kinds of atoms listed in the periodic table, with each kind constituting a...
What is a molecule? Despite being a standard scientific concept, it’s virtually impossible to agree a satisfactory definition, says Philip Ball In science, as in life, words often acquire meaning through usage rather than through definition. We use ‘species’ and ‘force’ without being ...
