How most eukaryotic genes are controlled
WebThe gene control in eukaryotic cells, particularly during differentiation is one of the most extensively studied areas in biology with special reference to molecular mechanism. The genes control the synthesis of various proteins in various cells which finally lead to differential gene expression. WebSpecifically, gene expression is controlled on two levels. First, transcription is controlled by limiting the amount of mRNA that is produced from a particular gene.
