Question

Complete the following sentences about DNA topology by moving the appropriate terms to their descriptions. is the coiling, or looping, of the double helix around its axis. . which results from the partial unwinding (right-handed winding or underwinding) of the double helix represents the topology of DNA in vivo and permits easier strand separation is the winding of the two DNA strands around each other permits DNA to maintain a relatively stable conformation when the helix is slightly underwound or overwound. results from the overwinding of the DNA double helix. Writhe Twist Positive supercoiling Supercoiling Negative supercoiling

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.
