The two strands of DNA that make up the double helix are connected by hydrogen bonds between the base pairs. For DNA to replicate, it must continuously zip and unzip the two strands. If those strands were held together by anything stronger than a hydrogen bond (say covalent bonds), it would require too much energy to unzip them and DNA would not be able to replicate. Were they to be held together by anything weaker dipole-dipole or dispersion forces), they probably would not stay together at all.
DNA is double stranded. The two complementary strands are held together by hydrogen bonds. These hydrogen bonds are strong enough to hold the molecule together, but weak enough to be unzipped when during DNA replication. This process requires enzymes, but in the end, it produces two identical strands of DNA from one.
Hydrogen bonds are individually weak, but many of them form. Collectively, they are strong enough to stabilize the structures of large biological molecules such as DNA.
well they are weak bonds - easier to break so DNA replication is easier whereas if they were covalent bonds DNA replication would not be possible
hydrogen bonding play a very important role in DNA structure because it hold two strands of DNA together
To pair base structures
A water molecule is formed when two hydrogen atoms bind covalently to a single oxygen atom.
yes, hydrogen bonds are what connects the double helix together. hydrogen bonds for between the nitrogen bases on each DNA strand. nitrogen bases are: - Cytosine (C) - Thymine (T) - Guanine (G) - Adenins (A)
Hydrogen bonds are important to the body for several reasons. For one thing, they cause DNA to retain its double helix structure. Additionally, they contribute to the folding of proteins, which is necessary for proper protein function.
allows water molecules to stick together creating cohesion
Hydrogen bonds are strong intermolecular forces- weaker than covalent bonds that hold the molecules together. The diagram probaly shows molecules with otted lines from H atoms to an O or N aatom on an adjacent molecule.
hydrogen bonds hold DNA together
DNA helicases break the hydrogen bonds in the DNA molecule
Hydrogen Bonds
The bonds are called hydrogen bonds. You can find these bonds in the nucleotides of DNA.
Hydrogen bonds hold the DNA bases together!
Hydrogen bonds
Strong hydrogen bonds.
The strands of the DNA double helix are held together by hydrogen bonds
A water molecule is formed when two hydrogen atoms bind covalently to a single oxygen atom.
the hydrogen bonds btw nitrogenous bases leads to stability of the double helix
