How is a DNA molecule held together and separated by?
A DNA molecule is held together by its hydrogen bonds. The bonds are in between the bases of the molecule, for example cytosine and guanine. Because hydrogen bonds are weak, they are able to break apart easily and split when the molecule needs to be separated to bond with another DNA molecule for reproduction.
The two sides of the dna molecule are held together by what?
Hydrogen bonds between the purines and pyrimidines. A and T form 2 hydrogen bonds, and G and C form three.
Numbering the carbon atoms in the DNA sugar deoxyribose helps to?
Describe the molecule and discuss where specific bonds form.
The DNA molecule has both strong bonds and weak bonds which hold the molecule together. is this true or false?
True
In the replication of DNA what kind of molecule bonds with an unpaired cytosine mucleotide?
In the replication of DNA Thymine bonds with cytosine.
What kind of bond holds the two strands of a DNA molecule together?
hydrogen bonds. The other bonds are covalent bonds.
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.
What nucleotide bonds with guanine?
Guanine bonds to Cytosine in DNA through three hydrogen bonds. It also bonds to a Deoxyribose molecule in the backbone of the DNA molecule.
The two strands of a DNA molecule are held together by what?
Hydrogen Bonds
What holdes the two strands of a DNA molecule to each other?
Hydrogen bonds
Two hydrogen bonds connect adenine to this in the DNA molecule?
Thymine
What holds together 2 strands of a DNA molecule?
Hydrogen bonds.
