WebC. The X-ray diffraction pattern of dna discovered by Rosalind Franklin showed that DNA. A) contains alpha helices and beta sheets. B) is helical. C) is both helical and has a repeated pattern. D) contains beta sheets arranged in a repeated … A transcriptional activator is a protein (transcription factor) that increases transcription of a gene or set of genes. Activators are considered to have positive control over gene expression, as they function to promote gene transcription and, in some cases, are required for the transcription of genes to occur. … See more Activator proteins consist of two main domains: a DNA-binding domain that binds to a DNA sequence specific to the activator, and an activation domain that functions to increase gene transcription by interacting with … See more Activator binding to regulatory sequences Within the grooves of the DNA double helix, functional groups of the base pairs are exposed. The … See more • CRISPR activation • Bacterial transcription • Coactivator (genetics) • Eukaryotic transcription See more Regulation of maltose catabolism The breakdown of maltose in Escherichia coli is controlled by gene activation.
