The two strands of a DNA molecule are held together by what?
Hydrogen Bonds
The two polynucleotide chains in DNA molecule are attracted to each other by what?
Between nucleotides, there is a phosphodiester bond between the phosphate group of one nucleotide and the sugar of another nucleotide. Nucleotides (such as Adenine and Thymine) are held together on two strands of DNA through hydrogen bonding. This doesn't keep nucleotides together in a strand, but helps in the structure of two corresponding strands of DNA.
which best describes the structure of dna molecule?
Answer:Two strands of DNA link together
How are the nitrogen bases held together in the center of the DNA molecule?
The nitrogen bases bond A-T and C-G via hydrogen bonds. The bases are held together in the string by a backbone of alternating phosphate and sugar molecules.
What holds DNA bases together?
The bonds of the atom are covalent where as the bonds between the base pairs are hydrogen.
What holds two atoms in a hydrogen molecule?
The two hydrogen atoms in a hydrogen molecule are held together by a covalent bond.
What is the chemical structure of the molecule?
Each molecule has a specific structure.
What helps molecule stick together?
Hydrogen bonds
The two strands of a DNA molecule are held together by what?
Hydrogen Bonds
Is hydrogen always written as H2?
'H2' is a Hydrogen molecule (2 atoms of hydrogen joined together) - Hydrogen in its natural state (the gas) exists as the hydrogen molecule. A single atom of Hydrogen is just 'H'
What is h2 in chemistary?
H2 is one molecule of Hydrogen as found naturally. It is called H2 because in one molecule of Hydrogen there are Two atoms of hydrogen bonded together.
How is a molecule of hydrogen form from two hydrogen atoms?
Well with any element when two atoms are put together they are known as a molecule of that element. So one atom of hydrogen is known as one atom of hydrogen and two atoms of hydrogen is known as one molecule of hydrogen.
Why is the water molecule or a compound?
The water molecule is a compound of hydrogen and oxygen sort of fused together.
Hydrogen bonds hold the hydrogen atoms together in a hydrogen molecule?
Non polar bond between the two hydrogen atoms.
How do an atom of hydrogen and molecule of hydrogen differ?
A molecule of hydrogen is two atoms of hydrogen bonded together so that they share their single electrons, making them act as if they had a full s1 orbital in both atoms.
What kind of bond holds the two strands of a DNA molecule together?
hydrogen bonds. The other bonds are covalent bonds.
How is water H2O?
because it is 2 molecule of hydrogen bonded with a molecule of oxygen together giving water.
