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

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
