WebIn eukaryotic cells, the first stage of gene expression control occurs at the epigenetic level. Epigenetic mechanisms control access to the chromosomal region to allow genes to be turned on or off. These mechanisms control how DNA is packed into the nucleus by regulating how tightly the DNA is wound around histone proteins. WebGene expression is the process by which specific genes are activated to produce a required protein. The process is made up of the transcription and translation of DNA …
