Regulation of Gene Expression
Regulation of protein production is an important aspect of the
dogma
.
The

trp
operon
is a

The

Eukaryotic gene expression can be
at many stages, from the
nucleus
to the
cytoplasm
.
Multicellular organisms develop from a single-celled
to cells of many different types through
cell
,
cell
, and
morphogenesis
.
Differential distribution of
determinants
in the egg can lead to subsequent
of
embryonic
cells.
Expression of genes for tissue-specific proteins result in cell
, and leads to
observable

Genetic
mutations
that affect cell cycle control can lead to
.
mutations are generally needed for full-fledged
cancer
