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
Why does a double stranded molecule denature into two single stranded molecules when heated?
The heat breaks the hydrogen bonds that hold the nitrogenous bases together in the centre of the DNA molecule. However, the covalent bonds between the phosphate and deoxyribose sugar are not affected.
What must be broken for the DNA strand to separte?
DHISS DiKC
Te multiple relatively weak bonds between complementary nitrogenous bases that hold double stranded DNA together are known as?
Hydrogen bonds.
What makes up the middle of a DNA molecule?
The nitrogen bases make up the center of the two strands of a DNA molecule.

What type of bonds form between two nitrogenous bases?
covalent
Where do hyrdrogen bonds form in the DNA molecule?
across the nitrogenous bases, they form between the complementary base pairs Thymine and Adenine and also cytosine and guanine

What is contained in nucleic acids?
Nucleic acids are polynucleotides. They are composed of nucleotides, which join together through phospho-diester bonds, with forms the sugar-phosphate backbone of the nucleic acid, and also through hydrogen bonds, between two complementary nitrogenous bases (in the case of DNA).The nucleotides which make up nucleic acids are composed of the following: a phosphate group (PO4), a deoxyribose sugar (in DNA) or a ribose sugar (in RNA) and finally a nitrogenous base. In DNA the purine nitrogenous bases are: adenine and guanine. The pyrimidine nitrogenous bases are: thymine (which bonds with two hydrogen bonds to adenine) and cytosine (which bonds with guanine through three hydrogen bonds. In RNA uracil replaces thymine and there are no hydrogen bonds between the nitrogenous bases as RNA is a single stranded molecule.
What must be broken for the DNA strand to separte?
DHISS DiKC
What are the parts of a DNA moleclue?
The parts of DNA molecule are nucleotide, bases, and the hydrogen bonds. The nucleotide contains a pentose sugar, phosphate group, and nitrogenous bases. Bases contain pyrimidine and purine and the hydrogen bonds holds the chains of nucleotides.
What breaks the bonds between the nitrogen bases of the DNA molecule?
Your answer is "Helicase". This is the enzyme responsible for the unzipping of the DNA molecule, or in other words, the breakage of the bonds of its nitrogen bases.
How are complementary nitrogenous bases held together?
hydrogen bonds
Te multiple relatively weak bonds between complementary nitrogenous bases that hold double stranded DNA together are known as?
Hydrogen bonds.
What makes up the middle of a DNA molecule?
The nitrogen bases make up the center of the two strands of a DNA molecule.
Which pair of nitrogenous bases will form a bond in a DNA molecule?
Complementary nitrogen bases pair by means of hydrogen bonds. Refer to the related link below for an illustration.
