What type of bond is the arrow pointing to in this image of DNA?-Hydrogen Bond-Covalent Bond-Ionic Bond The image illustrates the structure of DNA, highlighting its double helix form. At the top of the image, a black arrow points downward to a simplified segment of the DNA structure. This segment features:1. **Nucleotide Bases**: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). These bases form the rungs of the helical ladder and pair specifically with each other (A with T, and C with G).2. **Phosphate Groups**: Represented as yellow circles, these are part of the DNA backbone, linking with the sugars to form the sides of the ladder.3. **Deoxyribose Sugars**: Shown as pentagons, these connect each nucleotide base to the phosphate group, creating a sugar-phosphate backbone.The diagram transitions into the traditional double helix representation, where the nucleotide bases form complementary pairs connected by hydrogen bonds, shown as rungs in the ladder structure. The double-stranded helix twists to form the familiar shape of DNA.

Question

What type of bond is the arrow pointing to in this image of DNA?

-Hydrogen Bond
-Covalent Bond
-Ionic Bond

The image illustrates the structure of DNA, highlighting its double helix form.

At the top of the image, a black arrow points downward to a simplified segment of the DNA structure. This segment features:

1. **Nucleotide Bases**: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). These bases form the rungs of the helical ladder and pair specifically with each other (A with T, and C with G).

2. **Phosphate Groups**: Represented as yellow circles, these are part of the DNA backbone, linking with the sugars to form the sides of the ladder.

3. **Deoxyribose Sugars**: Shown as pentagons, these connect each nucleotide base to the phosphate group, creating a sugar-phosphate backbone.

The diagram transitions into the traditional double helix representation, where the nucleotide bases form complementary pairs connected by hydrogen bonds, shown as rungs in the ladder structure. The double-stranded helix twists to form the familiar shape of DNA.
