The DNA is the main thing that copies our genetics from our parents. Their shape is like a twisted ladder, also known as a double helix. They have four nucleotides: adenine, guanine, thymine, and cytosine.
DNA structures are connected by little small bars of deoxyribose sugar. They are carried by pairs of nucleotides. Each pair will never be separated, because each pair is the same as another. Adenine and thymine will always be a pair, and so will guanine and cytosine. Their structure is a double helix. I don't know why, but I do have a theory. My theory is the reason why it is a double helix is because it helps transfer the deoxyribose sugar faster. The spirals of the helix makes the it more flexible, fluid, and smooth, making the sugar go up or down easily. Think of a twisty slide. If the slide was straight, then it wouldn't be as smooth as it was before. The twist of the slide helps by making it smoother, because of the flexibility.
The structure of DNA took many years to figure out. A woman scientist, called Rosalind Franklin, took many years and days to find the information. She took X-rays, and she drew what she discovered in her little notebook. DNA is what makes us different, and what gives us our similarities. So to conclude it, the structure of DNA is a double helix.
