DNA is made up of double and triple bonds. If you remember the nitrogenous basis i.e. adenine. guanine, cytosine and thymine, where adenine pairs with thymine by double bond and guanine pairs with cytosine with triple bonds.

∙ 13y agoA little confused by the question, but here are possible answers:
1) Nucleic acids are a linear, unbranched polymer of nucleotide monomers. Nucleotides consist of a phosphate group, ribose, and nitrogenous base. Both the phosphate group and the nitrogenous bases contain double bonds.
2) DNA exists as a double strand (dsDNA). Among the interactions that holds the two single strands together is hydrogen bonds between the complementary bases. The complementary bases have either two (A=T or A=U) or three (G≡C) hydrogen bonds between them.
3) RNA exists as a single strand, but it takes on conformations that are double stranded where the single strand pairs with itself. The double stranded portions are held together by the same types of interactions and bonds as dsDNA.

What is the weak chemical bonds important in holding the dna double helix together is the?
The chemical bond that holds the double helix together in DNA are the hydrogen bonds. Hydrogen bonds are the weakest making them perfect for DNA replication.
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 type of bonds make p DNA and where in DNA do you find these bonds?
The bonds are called hydrogen bonds. You can find these bonds in the nucleotides of DNA.
True or false Helicases unwind the double helix of DNA by breaking the nitrogen bonds that link the hydrogen bases?
Hydrogen bonds.
How do alkali solutions denature DNA?
DNA has a double helix structure. This double helix structure exists, as the bases form hydrogen bonds (Adenine-Thymine form 2 hydrogen bonds and Guanine-Cytosine form 3 hydrogen bonds). In an alkali environment (mostly NaOH is used) the hydrogen bonds between the bases will be broken by the hydroxylic group (OH). Due to the breakage of the hydrogen bond, the double helix is broken, so two single DNA strands are obtained. Meaning the DNA is denatured.
In DNA what bonds with what?
Guanine bonds with cytosine in DNA.
What are the base pairs when replicating DNA?
Adenine double-hydrogen-bonds to Thymine, while Guanine triple-bonds to Cytosine or other similar derivates ;)
How can you use helix in a sentence?
My DNA forms a double helix due to the hydrogen bonds present in it.
What is the weak chemical bonds important in holding the dna double helix together is the?
The chemical bond that holds the double helix together in DNA are the hydrogen bonds. Hydrogen bonds are the weakest making them perfect for DNA replication.
What keeps DNA together?
DNA is kept together by hydrogen bonds. The bonds connect the bases together and gives DNA its double helix shape.
The two strands of a DNA molecule are held together by?
The strands of the DNA double helix are held together by hydrogen bonds
Why does The double helix unzip in locations with lots of A-T pairs?
in the DNA the A-T pais have double H-bonds between them and G-T pairs have triple H-bonds,that's why its simpler to break two bonds instead of three bonds...so the DNA unzips from A-T pais mostly... -Krishna Bora,Madras Christian College
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.
Is DNA or RNA triple stranded?
DNA is generally double stranded and RNA is single stranded.
How does heating double stranded DNA separate the strands?
The DNA double helix is separated by an enzyme called DNA helicase. This enzyme unzips the double helix and the strands are then held apart by single-strand binding proteins. DNA polymerase then copies each parent strand of the DNA.
Where are hydro bonds located in the DNA strand?
In 1953,JAMES WATSON and FRANCIS CRICK porposed the model for the structure of DNA. According to them DNA molecule consist of two polynucleotide strands which are twisted around each other in the form of DOUBLR HELIX. The double helic looks like spiral staircase of uniform diameter. The two poly nucleotide strands held in their helical configuration by the hydrogen bonds present between them. ADDENINE always pair up with guanine and thymine is always pair up with cytosine.HYDROGEN BONDS are present between the ADDENINE and GUANINE , CYTOSINE and THYMINE. Two hydrogen bonds are present between the ADDENINE and GUANINE while three hydrogen bonds are present between CYTOSINE and THYMINE. Due to these hydrogen bonds DNA keeps its shape.
What are the rungs of DNA latters made of?
Two strands of nucleotides, paired by weak hydrogen bonds (the rungs) between the bases, from a double-stranded DNA. When bonded in this way, DNA forms a two-stranded spiral, or double helix. Note that adenine always bonds with thymine and cytosine always bonds with guanine.
