Inhibit gene expression by binding to DNA and blocking transcription
Phenotypic differences in cells and organisms
Due to the combination of genes that are expressed
Gene expression differences account for phenotypic differences between organisms
Interaction of promoters and transcription factors
Determine phenotypic differences between tissues within an organism or between individual organisms
Small RNA molecules
Regulate gene expression post-transcription by either blocking transcription or by breaking down messenger RNA
Promoters are sequences upstream of the transcription start site where RNA polymerase and transcription factors bind to initiate transcription
Eye tissue cells contain regulatory proteins that interact with transcription factors to initiate transcription
Interaction of promoters and other transcription factors helps determine phenotypic differences between tissues within an organism or between individual organisms
Phenotypic differences in cells and organisms are due to the combination of genes that are expressed
Negative regulatory molecules inhibit gene expression by binding to DNA and blocking transcription
Small RNA molecules regulate gene expression post-transcription by either blocking transcription or by breaking down messenger RNA
