Bases of DNA are linked together by intermolecular forces are called?
The two strands of DNA are linked together by hydrogen bonds which occur between the nitrogen bases opposite one another along the molecule.
What best describes the structure of a DNA molecule?
A double helix of two strands of DNA linked together with sugar-phosphate backbones with bases on the inside.
Why does DNA have to have hydrogen bonds?
The hydrogen bonds between complimentary nitrogen bases hold the two strands of DNA nucleotides together.
What type of bond holds bases together?
Hydrogen bonds hold the DNA bases together. There are three bonds between Guanine and Cytosine, and two bonds between Adenine and Thymine.

The bases of the two DNA chains are linked in the middle of molecules by?
Complementary bases in DNA are held together via hydrogen bonds. Between G and C there are three hydrogen bonds and between A and T there are two hydrogen bonds.
How are the four bases of DNA linked?
Bases in DNA are linked through hydrogen bonds. There are two hydrogen bonds between Adenine and Thymine There are three hydrogen bonds between Guanine and Cytosine
Which best describes the structure of a DNA molecule-?

What are the two sections of DNA?
There are three main section of a DNA molecule. The nitrogenous bases. Four in number. Guanine linked to cytosine and thymine linked to adenine. The deoxyribose sugar. The phosphate group backbone.
What holds the two halves of a DNA double helix together?
Its Hydrogen Bonds that hold the two strands of the DNA double helix together.
What is a A-T Base?
'A-T' is two bases of DNA, Hydrogen-bonded together.
