First off - it is important to understand that a nucleotide (the monomer of DNA) is composed of 3 things: a sugar, a phosphate group, and a nitrogenous base. Next - understand that the "backbone" of DNA is composed of the sugars and phosphates.
That leaves you with nitrogenous bases. Hydrogen bonds form between the nitrogenous bases off opposite strands in the double helix. THIS is what holds the double helix together.
What else can I help you with?
What holds the two halves of a DNA double helix together?
The two halves of a DNA double helix are held together by hydrogen bonds between complementary nitrogenous bases. Adenine pairs with thymine and guanine pairs with cytosine. This base pairing allows for the specificity and stability of the DNA molecule.
What holds the two strands of a DNA molecule of each other?
Hydrogen bonds
What organelle holds genetic information in the molecule DNA?
The nucleus is the organelle that holds genetic information in the form of DNA. DNA is tightly packed into structures called chromosomes within the nucleus of eukaryotic cells.
What is the name of the sugar molecule in the DNA helix?
The sugar molecule in DNA is called deoxyribose. It is a five-carbon sugar that forms the backbone of the DNA molecule, connecting the nucleotide units together.
What type of bond holds the deoxyribose and phosphate together?
A phosphodiester bond holds the deoxyribose sugar and phosphate group together in a DNA molecule. This bond forms between the 3' carbon of one deoxyribose and the 5' carbon of the adjacent deoxyribose in the DNA backbone.
What holds together 2 strands of a DNA molecule?
Hydrogen bonds.
What is a single helix molecule?
A single helix molecule is a molecule that has a spiral shape resembling a single coil or spring. One common example is the DNA molecule, which consists of a single helix structure formed by its two intertwined strands.
What holds two strands of dna molecule to each other?
The two strands of DNA are held together by hydrogen bonds between the nitrogen base pairs.
The types of helixes found in DNA?
a double helix
What kind of bond holds the two strands of a DNA molecule together?
hydrogen bonds. The other bonds are covalent bonds.
What holds the strands of a DNA molecule to each other?
Hydrogen bonds
What can be found on the side parts of the ladder-like DNA molecule?
On the side parts of the ladder-like DNA molecule, you will find the sugar-phosphate backbone, which provides structural support to the molecule. The sugar-phosphate backbone serves as the outer framework that holds the nitrogenous bases together in the DNA double helix.
What holds the two halves of a DNA double helix together?
The two halves of a DNA double helix are held together by hydrogen bonds between complementary nitrogenous bases. Adenine pairs with thymine and guanine pairs with cytosine. This base pairing allows for the specificity and stability of the DNA molecule.
What holds the two strands of DNA molecule each other?
hydrogen bonds
What holds the strands of DNA together?
Hydrogen bonding.
What holds a single DNA strand together?
the nucleus
What holds the two strands of a DNA molecule of each other?
