How Does a Eukaryotic Cell Deal with the Superhelical Tension

question 3

Multiple Choice

How does a eukaryotic cell deal with the superhelical tension in its genomic DNA resulting from the activity of RNA polymerases?

• A) DNA gyrase introduces negative supercoils, keeping the DNA under constant tension.
• B) The RNA polymerases are allowed to rotate freely around their templates during transcription, leading to the relaxation of the tension.
• C) DNA topoisomerases rapidly remove the superhelical tension caused by transcription.
• D) The nucleosomes adjust the tension by binding to positively supercoiled regions behind a moving RNA polymerase.
• E) All of the above.

Definitions:

Stored Information

Stored information refers to data or knowledge that has been saved and can be retrieved from an individual's memory or a storage device.

Deterioration

The process of becoming progressively worse, often referring to the condition of objects, health, or environmental quality.

Depth-Of-Processing

Refers to the idea that information is more likely to be remembered depending on the level of cognitive processing it undergoes, with deeper, more meaningful processing leading to better retention.

Encoding-Specificity

The principle that memory retrieval is most effective when the cues at the time of recall match those present during encoding.
