Which of the following is true for gene regulation in both bacteria and eukaryotes? Selected answer will be automatically saved. For keyboard navigation, press up/down arrow keys to select an answer. a b Nucleosome structure and histone modifications affect the ability of transcription factors to bind to promoter and enhancer sequences. d Many genes need to be activated only in specific tissues and developmental stages. с Transcription is regulated by trans-acting proteins binding to cis-acting DNA sequences. Genes are often organized into operons, with one mRNA containing coding sequences for several proteins.
