In order to identify cis-regulatory elements for the BRC2 gene in Arabidopsis thaliana, you develop genetically-engineered alleles in which different sections of the upstream region are deleted (dashed segments in the diagram below). You evaluate the amount of mRNA produced by each allele compared to the wild-type sequence. The results are shown in the diagram below in comparison with the wild-type sequence. Match the following cis-regulatory elements with the correct region:
