Functionally related genes that are involved in the same biological pathways are often regulated by similar gene regulators (16, 17).
Alternative exons are often regulated according to cell-specific patterns and regulation is mediated by specific sets of cis-acting elements and trans-acting factors.
These rhythms are often regulated by short exposure to light.
The extent of liability is often regulated by contract.
So much of successful children's literature, for all ages, is based round this basic device of giving the power back to the children, whose lives are so often regulated by others.
Translation of eukaryotic mRNAs is often regulated by nucleotides around the start codon.
The provision of services is often regulated by means of agreements that must be negotiated beforehand.
Switching between alternative complex phenotypes is often regulated by "supergenes," polymorphic clusters of linked genes such as in butterfly mimicry.
In addition, these systems are often regulated in response to the presence of metal ions that in turn activates transcription of subsequent resistance determinants.
Intracellular biological processes are extremely complex, and are often regulated by two or more histone modifiers in a co-ordinated manner.
For instance, aspects of regeneration are often regulated by complex mechanisms of activation for several growth regulatory pathways in damaged tissue.
