Supercoiling is important for DNA structure, because
A) it holds together the antiparallel strands of DNA in the double helix.
B) it provides energy for transcription.
C) it condenses the DNA so that it can fit inside the cell.
D) it prevents RNA from pairing with DNA in the double helix.

Question

Quizplus · Accepted Answer

Supercoiling condenses the DNA so that it can fit inside the cell. This is important because DNA molecules are often very long and would not be able to fit inside the cell without being compacted. Supercoiling helps DNA molecules be condensed into a smaller space, which is important for proper cellular function.
