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.
What elements are H2?
H2 Is a diatomic hydrogen molecule. It is made up of two hydrogen molecules that are joined together.
What holds the molecules in solid together?
Water molecules are held together by hydrogen bond which is formed between hydrogen of one molecule and oxygen of other molecule. H2O-----H-O-H
Each water molecule is joined to?
Each water molecule forms multiple hydrogen bonds with neighboring water molecules. These bonds are transient and easily and quickly shift among molecules.
What type of bonds hold the bases together in a molecule of DNA?
Hydrogen bonds (two between adenine and thymine, and three between guanine and cytosine).
How many hydrogen bond hold guanine and cytosine?
The Adenine (Thymine) base pair is held together by 2 hydrogen bonds while the Guanine (Cytosine) base pair is held together by 3 hydrogen bonds. That is also the reason why the two strands of a DNA molecule can be separated more easily at sections that are densely populated by A - T base pairs.
How many water molecules bond together to form an ice crystal?
how many water molecules bond together to form an ice crystal
What is primarily responsible for holding water molecules together in the liquid state?
Hydrogen bonds caused by the polar properties of a water molecule.
Why is a compound different from an element?
a compound is many elements mashed together into one. water is H2O and is a compound. H2 for 2 hydrogen molecules, and O for 1 oxygen molecule. Oxygen is an element. When you give 1 oxygen molecule 2 hydrogen molecules it becomes a compound.
What is adenine and guanine held together with?
The Cytosine, Guanine, Adenine and Thymine bases present in DNA are molecules that are held together by intermolecular hydrogen bonds. This bond occurs between an electronegative atom (known as a hydrogen bond acceptor) and a hydrogen atom attached to another electronegative atom (known as a hydrogen bond donor).
What type of bonds hold one molecule of water to another molecule of water?
A hydrogen bond is the attractive interaction of a hydrogen atom with an electronegative atom(<-wikipedia). Hence, in a water molecule the positive hydrogen atoms are attracted to the negative oxygen atoms. Just know that the hydrogen bond mentioned above is not a chemical bond. If it were, it wouldn't be water anymore. Another force between water molecules are London Dispersion Forces.
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.
