- The bonds that holds the two strands of DNA come from where? What type of bond hold two strands of DNA together? Is Each strand in the double helix is identical to the opposite strand? No. Each base (A, G, T, C) pair with their respective base on the opposite strand making them exact opposites of each other.

What holds the bases together in DNA? Best Answer: Dna is a double helical structure with two strands of nitrogenous bases being held together by hydrogen bonds. Phosphodiester bonds hold bases together on the same strand. Between deoxyribose and a phosphate group. Hydrogen bonds hold the two strands together. Adenine and Thymine have 2 H bonds always.

What Type of Chemical Bond Holds DNA Strands Together? Hydrogen bonds hold DNA strands together. Nitrogenous bases are between these two strands that link together in a specific manner with different types of hydrogen bonds. A DNA molecule is made up of the sugar deoxyribose, a phosphate group and complementary nitrogenous base pairs. The double strand of the helix consists of the sugar-phosphate backbone. The nitrogenous base pairs, which are linked by hydrogen bonds that also hold the strands together, are between this backbone.

- Here, we look at how hydrogen bonds in DNA contribute to the overall stability of the DNA double helix structure. slide 1 of 4. Deoxyribonucleic acid, or DNA, is a polymer of nucleotides linked together by specific bonds known as phosphodiester bridges. The phosphate group (PO3) of one nucleotide links to the hydroxyl group (OH) of the following nucleotide. Hundreds of millions of these linkages occur within the DNA polymer.

Structural Biochemistry/Chemical Bonding/Hydrogen bonds Structural Biochemistry/Chemical Bonding/Hydrogen bonds - Hydrogen bonding in DNA. 1  DNA contains four bases:Guanine, Cytosine, Adenine, and Thymine. The complementary base pairs of guanine with cytosine and adenine with thymine connect to one another using hydrogen bonds.

- The strong bonds between the DNA chains are the hydrogen bonds (H-bonds). The H-bonds exist between the base pairs. 2 H-bonds exist between Adenine and Thymine and only 3 H-bo … nds exist between Guanine and Cytosine. This means that A-T bonds are stronger than C-G, this difference arises purely because of slight chemical differences in the bases. Within the chains the strong bonds are covalent. These covalent bonds are found between the sugar group of one nucleotide and the phosphate group of another.

- The DNA double helix is held together by two types of bonds, covalent and hydrogen. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing. These hydrogen bonds are individually weak but collectively quite strong. 3.

- So there are hydrophobic bonds that stabilize the DNA molecule along with the hydrogen bonds. Since these hydrophobic bonds permit some stable structures to form in single stranded DNA molecules, I can't say that all of the bonds that hold together a single strand of DNA are covalent.

- The nucleotides within each strand are held together by the phosphodiester bonds between the 5' carbon of one nucleotide and the 3 ' carbon of the adjacent nucleotdie. These strong covalent bonds form the the glue that holds the sugar/phosphate backbone together and thus act to keep each strand together.
