Answer:
The promoter
Explanation:
The promoter region is the region of DNA sequence which the RNA polymer binds to to initiate transcription. In the archae and eukaryotes, the core portion of the promoter region is called the TATA BOX. The promoter region is also located upstream of the DNA and can about a 100-1000 base pairs long.

<span>The mitochondria in eukaryotic cells originated from prokaryotic cells, bacteria that were once free-living. The mitochondria have their own DNA, which is inherited from the mother in most species. Similarly, plant cells have organelles called plastids which contain their own DNA and originated from free-living bacteria. The chloroplasts in plant cells, which convert the energy of sunlight into chemical energy via photosynthesis, are a kind of plastid, and they originated from bacteria that could do photosynthesis.</span>
