What type of chemical bond holds the bases of the two strands of Dna together?

Hydrogen bonds are one of the weakest bonds, and aren't even true bonding of molecules, but rather a magnetic attraction between them. This particular bond is what allows the base pairs of DNA to properly link, as Adenine and thymine bond, and cytosine and guanine bond, but neither of these pairs bonds with elements from the other pair in this way.

Hydrogen bonds are the one type of bond that holds together the DNA 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 structure holds two strands of DNA together after replication until metaphase of mitosis?
Centremere?
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.
What holds the two helixes in a DNA molecule together?
First off - it is important to understand that a nucleotide (the monomer of DNA) is composed of 3 things: a sugar, a phosphate group, and a nitrogenous base. Next - understand that the "backbone" of DNA is composed of the sugars and phosphates. That leaves you with nitrogenous bases. Hydrogen bonds form between the nitrogenous bases off opposite strands in the double helix. THIS is what holds the double helix together.
What type of bonds holds the nitrogenous bases together in the DNA molecule?
your teacher will probably accept hydrogen bonds, however it is more of an attraction not a physical bond
What holds the bases together between the two strands?
hydrogen bonds
What type of chemical bond holds the double strands of Dna together?
Hydrogen bonds do this.
How do they bond within each other across strands?
I assume you mean the hydrogen bonding that holds bases of DNA together.
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 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.
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 holds the strands of DNA together?
Hydrogen bonding.
What type of bonding holds the two strands of DNA together and why is this important?
hydrogen bonding between the two bases present on two strands of dna hold the two strands. If there was no hydrogen bonding then doublex helix structure of dna would not be possible
What holds together the 2 strands of DNA?
Hydrogen bonds
Type of pairing that holds together the strands of DNA?
hydrogen bonds
What holds together 2 strands of a DNA molecule?
Hydrogen bonds.
What type of bonds holds DNA strands together?
DNA strands are held together by hydrogen bonds.
