Regulation of Gene Expression in Eukaryotes MCQ




In eukaryotes, regulation of gene expression is a complex process that controls when and to what extent genes are transcribed and translated into proteins. This regulation involves various mechanisms, including transcription factors, chromatin remodelling, RNA processing, and post-translational modifications, ensuring precise control of cellular functions and responses to environmental cues. This MCQ on Regulation of Gene Expression in eukaryotes will help you to study the concept very well.
