3. This is a transcription factor with the of job of binding a specific sequence of DNA (DNA binding domain, DNA in yellow) and also recruit other factors to allow transcription (regulatory domain). This is a quaternary structure: a dimer, two copies of the protein are required to interact to make a functional transcription factor (one is red and the other blue). What do think the result would be if the cell acquired a mutation that only allowed translation of the DNA-binding domain, which could still dimerize? .
