How do the bases pair in DNA to form the double helix structure?
In DNA, the bases pair up in a specific way to form the double helix structure. Adenine pairs with thymine, and guanine pairs with cytosine. This pairing is important for maintaining the structure and stability of the DNA molecule.
Can RNA form a double helix structure?
No, RNA cannot form a double helix structure like DNA.
How do the bases pair up in DNA to form the double helix structure?
In DNA, the bases pair up in a specific way to form the double helix structure. Adenine pairs with thymine, and guanine pairs with cytosine. This pairing is called complementary base pairing, and it helps stabilize the structure of the DNA molecule.
How does DNA form a double helix structure?
DNA forms a double helix structure through the pairing of complementary nucleotide bases. Adenine pairs with thymine, and guanine pairs with cytosine, creating a stable and twisted ladder-like structure. This pairing is held together by hydrogen bonds, resulting in the iconic double helix shape of DNA.
What molecules form the sides of the double helix?
The sides of the DNA double helix are formed by alternating sugar (deoxyribose) and phosphate molecules, which make up the backbone of the structure. The sugar-phosphate backbone provides stability and support for the nitrogenous bases in the center of the helix.

Does DNA have bases on the interior of the double helix?
Yes, DNA bases are located on the interior of the double helix structure. The bases pair up with each other across the two strands of DNA to form the rungs of the DNA ladder-like structure. This base pairing is crucial for maintaining the integrity and functioning of the DNA molecule.

The sides of the DNA double helix are formed by alternating sugar (deoxyribose) and phosphate molecules, which make up the backbone of the structure. The sugar-phosphate backbone provides stability and support for the nitrogenous bases in the center of the helix.
What is the primary structure of DNA?
The primary structure of DNA refers to its linear sequence of nucleotides, which are made up of a sugar-phosphate backbone and nitrogenous bases. The four bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G), which pair up to form the double helix structure of DNA.
How many sugar phosphate backbones does a double helix have?
A double helix structure has two sugar-phosphate backbones, one on each side of the helix. These backbones are made up of alternating sugar and phosphate molecules that support the DNA bases in the helix.
Where is the nitrogen atom in a double helix?
Nitrogen atoms are present in the nucleotide bases that make up the rungs of the DNA double helix. Specifically, the nitrogen atoms are found within the purine (adenine, guanine) and pyrimidine (cytosine, thymine) bases that pair with each other to form the double helix structure.
What type of bonding do the nitrogenous bases form?
Nitrogenous bases form hydrogen bonds with one another. These hydrogen bonds are responsible for holding the two strands of DNA together in the double helix structure.
What kind of bond holds the two strands of the double helix together?
Hydrogen bonds that form between the nitrogenous bases hold the double helix together.
Can nucleotides be linked together to form a double helix?
Yes, nucleotides can be linked together to form a double helix structure through bonding between complementary base pairs. The double helix structure is a characteristic of DNA, where two nucleotide strands are connected by hydrogen bonds between adenine-thymine and guanine-cytosine base pairs.
