Web26 mrt. 2024 · It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. WebTags: Epigenetics. Eukaryotic DNA is packaged and wrapped around proteins known as histones which protect and regulate gene expression. The structure of DNA wrapped around histone octamers is known as chromatin. Chromatin at the first level of its organization appears as a linear array of uniform structural units, nucleosomes. meaning of seeing a red headed woodpecker
