Brassinolide binding to the brassinosteroid receptor kinase

BRASSINOSTEROID-INSENSITIVE1 (BRI1) on the plasma membrane triggers a phosphorylation cascade that causes a repressor protein, BRASSINOSTEROID-INSENSITIVE2

(BIN2), to become inactivated. This results in activation of the transcription factors BRI1-EMS SUPPRESSOR1 (BES1) and BRASSINAZOLE-RESISTANT1 (BZR1) and subsequent gene expression

By counting the number of sites to which ORC binds, we can estimate that there are about 400 origins of replication in the yeast genome. This means that the average length of a replicon is -35,000 bp.

Large aberrations can be detected by examination of mitotic chromosomes that have been stained with banding agents such as quinacrine or Giemsa.
