Answer: DNA is unwound.

Explanation:

DNA replication is the process where by two identical DNA copies are produced from a double stranded DNA molecule.

Before DNA will replicates, the double helix length of the DNA to be copied must be unwound, the two strands are separated and the hydrogen bond that link the paired bases are broken. Once the are unwound, they are held apart to expose the new bases so that hydrogen bond can link the nucleotides. The enzyme polymerase then join the new nucleotides into a new DNA strand that is complementary to the template.

If you are driving down the road, how do you know that the car is moving (think about your reference point)?
NISA [10]
If your car is changing speed by accelerating or decelerating, or changing directions by turning or hitting a bump, your body can sense these accelerations. You might be pressed against the back of your seat while speeding up or against the car door as you turn for example. If you are cruising at a constant speed, with no changes in speed or direction, you wouldn't be able to feel it. You would need to use your other senses. You could see the scenery going by through the windows, with closer objects moving by more quickly than objects in the distance. You could also hear sounds like the wind rushing by and the hum of the tires rolling on the highway.
