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.
Hydrogen bonds connect the nitrogenous bases in the double helix of DNA.
The weak chemical bond important in holding the DNA double helix together is the hydrogen bond. These bonds form between the nitrogenous bases of the two DNA strands, specifically between adenine and thymine, and guanine and cytosine. The hydrogen bonds provide stability to the double helical structure of DNA.
Hydrogen bonds connect the nitrogenous bases in the double helix of DNA.
Thymine hydrogen bonds help hold the two strands of DNA together in a double helix structure by forming specific bonds with adenine on the opposite strand. These hydrogen bonds provide stability to the overall DNA structure.
False. Helicases unwind the double helix of DNA by breaking the hydrogen bonds between the nitrogenous bases, not the nitrogen bonds that link the bases.
My DNA forms a double helix due to the hydrogen bonds present in it.

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.
Hydrogen bonds connect the nitrogenous bases in the double helix of DNA.
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.
Thymine hydrogen bonds help hold the two strands of DNA together in a double helix structure by forming specific bonds with adenine on the opposite strand. These hydrogen bonds provide stability to the overall DNA structure.
DNA can form triple-stranded structures, although this is not common in nature. RNA can also form triple-stranded structures, particularly in certain non-canonical forms of RNA. Overall, triple-stranded structures are less common than the more prevalent double-stranded forms of DNA and RNA.
False. Helicases unwind the double helix of DNA by breaking the hydrogen bonds between the nitrogenous bases, not the nitrogen bonds that link the bases.
DNA is held together by hydrogen bonds between the nitrogenous bases adenine (A) and thymine (T), as well as cytosine (C) and guanine (G). These base pairs form the rungs of the DNA double helix, providing stability to the overall DNA structure.
