The inheritance of gene expression patterns, in the absence of the initiating signal, is called Epigenetic regulation.

Epigenetic changes can be defined as inherited variations which are not present in the DNA sequence. Gene expression is regulated at different levels and not merely in response to DNA modifications. Examples of epigenetic control include DNA methylation, histone deacetylation and mi-RNA expression.

Epigenetic mechanisms add an adaptive layer of control in the regulation of gene expression that allows an organism to adapt to a dynamic environment.

Epigenetic regulation increases the functional intricacy of deoxyribonucleic acid (DNA) by changing chromatin structure, nuclear organization as well as transcript stability.

Answer:

Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ''read'' the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases.
