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. (C) Transcription. (A) What is Gene Expression?. (B) Structure and Functions of RNA. Gene Expression.
