DNA is a double-stranded molecule twisted into a helix (think of a spiral staircase). Each spiraling strand, comprised of a sugar-phosphate backbone and attached bases, is connected to a complementary strand by non-covalent hydrogen bonding between paired bases. The bases are adenine (A), thymine (T), cytosine (C) and guanine (G). A and T are connected by two hydrogen bonds. G and C are connected by three hydrogen bonds.
What else can I help you with?
What are the two sides of the DNA and the helix held by?
The two sides of DNA are the sugar-phosphate backbone, which provides the structural support for the molecule. The helix is held together by hydrogen bonds between the nitrogenous bases on each side of the DNA molecule.
Two sides of DNA ladder are loosely bonded together by what?
by weak hydrogen bonds :)
What is the chemical interaction that holds two stands of a DNA double helix together?
The chemical interaction that holds two strands of a DNA double helix together is hydrogen bonding. Adenine pairs with thymine, and guanine pairs with cytosine through specific hydrogen bond interactions, forming the base pairs that stabilize the double helical structure of DNA.
What holds DNA base pairs together until it is time to replicate?
The two strands of DNA are held together by hydrogen bonds.
What type of intermolecular force holds together DNA strands in your body?
Hydrogen bonding is the primary intermolecular force that holds together the two strands of DNA in your body. These hydrogen bonds form between complementary base pairs (adenine-thymine, guanine-cytosine) and contribute to the stability of the DNA double helix structure.
What hold the side of DNA ladder together?
what holds the sides of the DNA ladder together
What color is the bond that holds two stands of DNA together?
Colourless.
What are the two sides of the DNA and the helix held by?
The two sides of DNA are the sugar-phosphate backbone, which provides the structural support for the molecule. The helix is held together by hydrogen bonds between the nitrogenous bases on each side of the DNA molecule.
What are the two sides of the DNA helix held together by?
Hydrogen bonds.
What type of bonding holds the two strands of DNA together?
hydrogen bonds
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 two strands of dna molecule to each other?
The two strands of DNA are held together by hydrogen bonds between the nitrogen base pairs.
What is the area in the center of the chromosome which holds the two sides together?
The area in the center of a chromosome that holds the two sides together is called the centromere. The centromere is responsible for ensuring that the duplicated chromosomes are divided evenly during cell division. Its function is crucial for the accurate segregation of genetic material.
What structure holds two strands of DNA together after replication until metaphase of mitosis?
The structure that holds two strands of DNA together after replication until metaphase of mitosis is the centromere. The centromere is a region of the chromosome where the two sister chromatids are held together and is essential for proper chromosomal segregation during cell division.
Two sides of DNA ladder are loosely bonded together by what?
by weak hydrogen bonds :)
What type of bonding holds the two strands of DNA together and why is this important?
hydrogen bonding between the two bases present on two strands of dna hold the two strands. If there was no hydrogen bonding then doublex helix structure of dna would not be possible
What is the chemical interaction that holds two stands of a DNA double helix together?
The chemical interaction that holds two strands of a DNA double helix together is hydrogen bonding. Adenine pairs with thymine, and guanine pairs with cytosine through specific hydrogen bond interactions, forming the base pairs that stabilize the double helical structure of DNA.
