Common variants (not necessarily disease-causing) are known to exist in coding and regulatory sequences of genes.

There is also a regulatory sequence 3' to the editing site.

Discussion This work describes two principles for analyzing combinations of regulatory sequences.

An example of a cis-acting regulatory sequence is the operator in the lac operon.

Several regulatory sequences in the promoter region of the human insulin gene bind to transcription factors.

These mutations often occur in oncogenes or regulatory sequences.

In addition to detecting previously unidentified genes and regulatory sequences, improved quantification of transcription products is possible.

High GC-content is also seen in regulatory sequences such as promoters which signal the start of a gene.

The human genome has many different regulatory sequences which are crucial to controlling gene expression.

However, regulatory sequences disappear and re-evolve during evolution at a high rate.
