When two strands of DNA that have exactly complementary base pairing (Adenine bonds with only Thymine, and Cytosine with Guanine) the base forms a hydrogen bond to the base on the opposite strand, only if the base pairing is complementary. So, in short the double helix form is held together by hydrogen bonds between the bases present on the strand.

This means as the two strands are split apart, a new complimentary strand is formed against each, resulting in two identical double helices where there was just one before. It is by this means that the instructions for the code of life are copied and passed on.

What is the chemical interaction that holds two stands of a DNA double helix together?

The chemical interaction that holds two strands of a DNA double helix together is hydrogen bonding. Adenine pairs with thymine, and guanine pairs with cytosine through specific hydrogen bond interactions, forming the base pairs that stabilize the double helical structure of DNA.


What type of bond holds together 2 strands of DNA?

Hydrogen bonds hold together the two strands of DNA. These bonds form between specific base pairs: adenine (A) with thymine (T), and guanine (G) with cytosine (C), creating the double helix structure of DNA.


. How are complementary strands of DNA held together?

Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.


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 is involved in the inter-chain linkage between complementary strands of DNA?

Inter-chain linkage in DNA involves hydrogen bonding between complementary nitrogenous bases (A-T and C-G) on opposite strands. This forms a stable double helix structure. The sugar-phosphate backbones of the two strands run antiparallel to each other, creating a strong and stable connection between the two DNA strands.


Why weak bonds are important to living organisms?

Weak bonding forces, such as hydrogen bonding are essential to living organism because these bonds can be broken and re-made fairly easily. The two strands of DNA are held together in a double helix by hydrogen bonds.

What is the bond that connects two strands together?

The bond that connects two strands of DNA together is called a hydrogen bond. These bonds form between complementary nitrogenous bases (adenine-thymine and cytosine-guanine) on each strand, holding the two strands together in a double helix structure.


Why does the DNA zip up again?

After DNA replication, the two strands of DNA that were separated during that process come back together to form the double helix structure. This is facilitated by hydrogen bonding between the complementary base pairs (A-T and G-C) on the two strands. Additionally, the twisting of the DNA molecule helps the strands coil back together.
