Ribonucleic acid (RNA) is a key nucleic acid in transcription and translation. RNA is like DNA except that:. Understanding:. Gene expression is regulated by proteins that bind to specific base sequences in DNA . The environment of a cell and of an organism has an impact on gene expression. Nucleosomes help to regulate transcription in eukaryotes. DNA directs the activities of the cell by controlling the proteins the cell produces.. This determines what the cell becomes, what it synthesizes, and how it functions. Gene Protein occurs in 2 steps Transcription and Translation. Geeta. . Narlikar. ) . .
