Explanation / Answer

Writhe is the coiling, or looping, of the double helix around its axis.

Negative supercoiling, which results from the partial unwinding of the double helix, representing the topology of DNA in vivo and permits easier strand separation.

Twist is the winding of the two DNA strands around each other.

Supercoiling permits DNA to maintain a relatively stable confirmation whent he helix is slightly underwound or overwound.

Positive supercoiling results from the overwinding of the DNA double helix.
