The transcription terminator stops dna polymerase, and results in the polymerase falling off the dna template. adds a terminator nucleotide to the rna, and results in a hairpin loop structure in rna. stops dna polymerase, and adds a terminator nucleotide to the rna. results in a hairpin loop structure in rna, and stops dna polymerase. results in a hairpin loop structure in rna, and results in the polymerase falling off the dna template.

Results in a hairpin loop structure in RNA, AND results in the polymerase falling off the DNA template.

Explanation:

As the RNA polymerase arrives at the terminator site, it pauses. The termination of RNA transcription occurs when an RNA transcript with a self-complementary sequence is formed leading to the formation of the hairpin structure. The hairpin structure has 15-20 nucleotides.  

The hairpin structure of RNA weakens A=U base pairs in RNA-DNA hybrid and/or weakens the interaction between RNA and RNA polymerase. The overall effect is the dissociation of RNA polymerase from the complex and termination of the transcription.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
