Which of the following is NOT characteristic of a eukaryotic enhancer element?

#Unit 3. Fundamental Processes
  1. Its activity is independent of its orientation (i.e., the sequence can be inverted without effect).

  2. Its activity is dependent on its distance from the start site of transcription.

  3. It may be found as far as 1 to 2 kilobases from the promoter.

  4. It may be positioned at the 5’end or the 3’ end of the gene.

Oxygen-Evolving Organisms Have two Photosystems that Operate in Series, explain by emerson that is the Photosystem I preferentially absorbs far-red light of wavelengths greater than 680 nm; photosystem II preferentially absorbs red light of 680 nm and is driven very poorly by far-red light; Another difference between the photosystems is that,

a.) Photosystem I produces a strong reductant, capable of reducing NADP+, and a weak oxidant

b.) Photosystem I produces a very strong oxidant, capable of oxidizing water, and a weaker reductant than the one produced by photosystem II

c.) Photosystem II produces a strong reductant, capable of reducing NADP+, and a weak oxidant

d.) Photosystem II produces a very strong oxidant, capable of oxidizing water, and a weaker reductant than the one produced by photosystem I
