The chemical composition of a mineral determines its properties.
A mineral is a naturally occurring inorganic solid substance that has a definite chemical composition and characteristic physical properties. The definite chemical composition and internal atomic structure of a mineral directly determines its properties and outward appearance which can be used to identify the mineral. Minerals are composed of one or more elements. For example the mineral quartz has the elements silicon (Si) and oxygen (O) as its only constituents.
In order for a substance to be classed as a mineral it must be naturally occurring, solid and inorganic. Additionally, it must have a clearly defined structure and chemical composition.
<span>Messenger RNA (mRNA) is known
to be molecules that carries codes (DNA) in the nucleus to the cytoplasm the
sites of protein synthesis. Thus, it is the RNA copy from one section of the
DNA that usually correspond to a single
gene. </span>
