J. Promoter
Explanation: A transcription factor and its associated transcription mediator complex must be attached to a DNA binding site called a promoter region before RNAP can initiate the DNA unwinding at that position.
B. it had to have been in a warm area and then moved there by plate tectonics over time due to the warm-climate plant fossils found there
Explanation:
One evidence that suggests that ancient Antarctica was situated in a different location from today is seen in the warm-climate fossils plants found there.
- Antarctica today occupies the southern polar region of the earth.
- It the coldest region on earth with very extreme of cold.
- From the theory of continental drift proposed as subset of plate tectonics, the continent Antarctica was once a landmass in a tropical region with lush green plants.
