Hope this helps!
Answer:
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.
Answer: C)a branching chart that depicts evolutionary relationship among organisms
Explanation: Answer: A phylogenetic tree is a branching diagram or "tree" showing the inferred evolutionary relationships among various biological species or other entities—their phylogeny—based upon similarities and differences in their physical or genetic characteristics
hope it helps :) plus can i get brainliest?
Answer:
<em>Too much water accumulation leads to a condition called as water intoxication.</em>
Explanation:
Drinking too much water leads to a condition called water intoxication or water poisoning. This happens because the concentration of water becomes such abundant in a person's body that it dilutes the concentration of electrolytes like sodium in the blood. This causes a disruption in the functioning of the brain hence leading to the death of the person. Various such scenarios have been observed in athletes drinking too much water.
