All of the Following are True of Supercoiling in Chromosomal

Question

All of the following are true of supercoiling in chromosomal DNA EXCEPT that it
A) doubles back and twists upon itself.
B) facilitates RNA transcription.
C) results in compaction.
D) is generated by gyrase.
E) is maintained by DNA-binding proteins.

Accepted Answer

Supercoiling does not directly facilitate RNA transcription, but it does indirectly facilitate transcription by compacting the DNA and bringing the promoter region closer to the RNA polymerase.
