What is a ribosome?
A ribosome (see below) is one of the most fundamental
structures in all of biology. It is an
assembly of many different proteins and large
pieces of RNA, which make up two-thirds of its
mass and actuall
subatomic particles. All atoms of a particular element have
the same number of protons in their nuclei. This number
of protons, which is unique to that element, is called the
atomic number and is written as a subscript to the left
of the symbol for the el
examples. Each element has a symbol, usually the first letter
or two of its name. Some symbols are derived from Latin or
German; for instance, the symbol for sodium is Na, from the
Latin word natrium.
A compound is a substance consisting of two or more
scanners that can monitor growth and metabolism of cancers
in the body (Figure 2.5).
Although radioactive isotopes are very useful in biological
research and medicine, radiation from decaying isotopes
also poses a hazard to life by damaging cellular molec
