Bond type created by DNA ligase?
DNA ligase links together two DNA strands that have double-strand break (a break in both complementary strands of DNA). DNA ligase creates a phosphodiester bond to fully repair the DNA.
What part of the DNA backbone do nitrogen bases bond to?
Nitrogen bases in DNA bond to the deoxyribose sugar molecules that make up the DNA backbone. The bond between the sugar and the base is a covalent bond known as a glycosidic bond.
Why DNA duplex melts at a specific temperature on heating?
DNA duplex strands are bonded by hydrogen bonds. On heating the hydrogen bonds break. At specific temperature called Tm half of the double helix is broken down (separated from each other) while the other half remains as such. This temperature can be determined , also the GC bond is stronger than AT so in such cases the temperature is more if the helix has more GC bonds.
What is the type of bond cytosine and guanine make?
An H-bond, or known as hydrogen bond. Hydrogen bonds are attractive bonds, very strong but easy to break. Think of it as someone who has a girlfriend(a strong bond, connected) but is attracted to other girls. A hydrogen bond is not as strong as a covalent or ionic bond(a strong bond).
Which part of a deoxynucleoside triphosphate molecule provides the energy for DNA synthesis?
The triphosphate group of the deoxynucleoside triphosphate molecule provides the energy required for DNA synthesis. When one of the phosphate groups is cleaved, it releases the energy necessary for the formation of phosphodiester bonds between nucleotides during DNA replication.
What is the energy required to break one bond of DNA?
It depends on the bond. A carbon-carbon single bond requires on average 356 kilojoules per mole. A carbon-carbon double bond requires 598 kj/mol. A carbon-hydrogen bond requires 416 kj/mol. These numbers can be found in most general chemistry textbooks. Here is one set of tables. http://www.wiredchemist.com/chemistry/data/bond_energies_lengths.html Different tables have slightly different values.
What type of bond is found between the two side rails of DNA?
If you are talking about between the bases of DNA, then it is a Hydrogen bond. A hydrogen bond will break easily for replication when the helicase separates the DNA.
Bond type created by DNA ligase?
DNA ligase links together two DNA strands that have double-strand break (a break in both complementary strands of DNA). DNA ligase creates a phosphodiester bond to fully repair the DNA.
What type of bond is broken when mRNA separates from DNA?
When mRNA separates from DNA, the bond that is broken is a hydrogen bond.
What part of the DNA backbone do nitrogen bases bond to?
Nitrogen bases in DNA bond to the deoxyribose sugar molecules that make up the DNA backbone. The bond between the sugar and the base is a covalent bond known as a glycosidic bond.
In DNA what do phosphate groups bond to?
Phosphate groups in DNA bond to sugar molecules through a phosphodiester bond to form the backbone of the DNA strand.

Which form of radiation can break a bond in some molecules?
Ultra violet radiation does this all the time to DNA molecules. Thymine dimers are the result of this radiation on epidermis cells.
How does DNA ligase utilize ATP during the process of DNA repair and replication?
DNA ligase utilizes ATP during the process of DNA repair and replication by using the energy from ATP to catalyze the formation of a phosphodiester bond between the DNA strands, sealing any breaks or gaps in the DNA molecule.
Which part of a deoxynucleoside triphosphate molecule provides the energy for DNA synthesis?
The triphosphate group of the deoxynucleoside triphosphate molecule provides the energy required for DNA synthesis. When one of the phosphate groups is cleaved, it releases the energy necessary for the formation of phosphodiester bonds between nucleotides during DNA replication.
What do purines bond to?
Purines bond to pyrimidines in nucleic acid DNA .
