What enzyme is responsible for breaking the hydrogen bonds between the two strands and unwinding the helix?

Helicases and gyrases both function to uncoil the supercoiling of the two DNA strands. Moreover, gyrase is responsible for adjusting the tension in the two strands so that they don't snap while unraveling.

What is most directly responsible for water's unique properties?
Hydrogen bonds between the Oxygen of one molecule and the hydrogen of another :)
Which type of bond is responsible for water's cohesion and which atoms interact to form this bond?
A hydrogen bond between the oxygen of one water molecule and the hydrogen of another water molecule.
What chemical has a reaction to water?
Sodium will react with water by breaking the bonds between the hydrogen and oxygen, disassociating the hydrogen and oxygen and releasing them as free gasses, and in the process also releasing large amounts of energy in the form of heat, which is quite sufficient to ignite the hydrogen, such that the hydrogen and oxygen will burn at a high temperature. The result looks like the sodium is causing the water to burn.
Why water different from its components?
this because the chemical reaction between Oxygen & Hydrogen obviously the Hydrogen bonds between Oxygen & Hydrogen.
How do bonds form between water molecules?
The bond between water molecules is known as a hydrogen bond.
What enzyme is responsible for unwinding the DNA molecule for replication?
DNA Helicase is the enzyme responsible for unzipping DNA before replication occurs.
What is most directly responsible for water's unique properties?
Hydrogen bonds between the Oxygen of one molecule and the hydrogen of another :)
What type of bonding is responsible for maintaining the shape of the tRNA molecule?
hydrogen bonding between base pairs
Enzymes that open the double helix by breaking hydrogen bonds between nitrogen bases is what?
Helicase.
Which enzyme is responsible for facilitating the hydrogen bonding between nucleotides in a new molecule?
the DNA polymerase III
WHAT Breaks the hydrogen bonds in DNA?
i dont know but there is a website its wikipiedia
Which type of bond is responsible for water's cohesion and which atoms interact to form this bond?
A hydrogen bond between the oxygen of one water molecule and the hydrogen of another water molecule.
Is the attraction between sodium chloride and water a intermolecular force of an intramolecular bond?
its basically the hydrogen bonding mainly responsible for this attraction.
What forces between water molecules are responsible for many of water's unusual physical properties?
hydrogen bonds
The boiling temperature of water is so much higher than that of methane because water molecules are?
d.polarWater molecules are polar covalent and therefore form attractions between the molecules called hydrogen bonds. Much of the heat that goes into raising the temperature of water to its boiling point goes to breaking the hydrogen bonds first.
Why alkyl groups are o- and p- directing?
Because they donate the electrons to aromatic ring due to hyper conjugation (temporary bond breaking between carbon and hydrogen)
Why the boiling point of water is 100 while ammonia is -33?
Water's boiling point is due in large part to the hydrogen bonds between the water molecules. Energy must go into breaking the hydrogen bonds before the water can boil.
