Hydrogen bonds
cytosine and guanine form three hydrogen bonds between them
DNA strands are held together by hydrogen bonds that form between the nitrogen bases of both strands.
hydrogen bonds
Base pairs in DNA are attached to each other via hydrogen bonds. The base pairs are attached to the backbone by covalent bonds.
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
your teacher will probably accept hydrogen bonds, however it is more of an attraction not a physical bond
Thymine and adenine! Also guanine and uracil.
Hydrogen bonds
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.
Hydrogen Bonds
cytosine and guanine form three hydrogen bonds between them
Hydrogen bonds (H-bonds) are broken between the nitrogenous bases when the two strands of DNA separate. These bonds are not as strong as the covalent bonds holding together the sugar and phosphate in the backbone, so the H-bonds break first.
DNA strands are held together by hydrogen bonds that form between the nitrogen bases of both strands.
The hydrogen bonds between complimentary nitrogen bases hold the two strands of DNA nucleotides together.
