Non-coding sequence

A part of a gene which does not directly define the amino acid sequence of the corresponding protein. In higher organisms these sequences are ten times more numerous than coding sequences. Certain non-coding sequences are zones regulating gene activity, which allows for the corresponding protein synthesis to be activated, or on the contrary to inhibit it. But, beyond these regions, the roles of the majority of non-coding sequences remain unknown.
