Which type of chemical bonding holds the two strands of DNA together in the double helix?

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.

. How are complementary strands of DNA held together?
Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.
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 bond is responsible for holding the two strands of double stranded DNA together?
Hydrogen bonds are responsible for holding the two strands of DNA together.
What is the double coiled shape of DNA?
A molecule of DNA consists of two strands of various chemical compounds that other chemicals carrying genetic information join together, much like ladder rungs hold ladder rails apart. The two strands joined with thousands of rungs look like a long rope ladder that has been twisted into the shape of a spiral, called a double helix.
Which best describes the structure of a DNA molecule-?
a double helix- apex
What type of bond holds together 2 strands of DNA?
Hydrogen bonding holds together the two strands of a double stranded DNA. Hydrogen bonding exists between the nitrogen base pairs.
What type of chemical bond holds the double strands of Dna together?
Hydrogen bonds do this.
How can you recognize design in DNA?
dna is a double stranded structure consisting of two complementary strands which are held together by hydrogen bonding between the base pairs of the two strands
What is the bond that connects two strands together?
Hydrogen bonds hold the two strands of the double helix together.
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 indiviual strands of a double-stranded chromosome joined together by?
Chromatid
. How are complementary strands of DNA held together?
Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.
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 bond is responsible for holding the two strands of double stranded DNA together?
Hydrogen bonds are responsible for holding the two strands of DNA together.
What kind of bond holds the two strands of the double helix together?
Hydrogen bonds that form between the nitrogenous bases hold the double helix together.
The two strands of a DNA molecule are held together by?
The strands of the DNA double helix are held together by hydrogen bonds
What are two molecules found in living things besides water that depend on hydrogen bonding for their structure and function?
The cohesion between strands of the DNA double helix and the primary structure of proteins are both dependent on hydrogen bonding.
