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.
How are DNA molecules bound together to form a double helix?
The DNA strands are held together by hydrogen bonds between complimentary base pairs.
What causes the two sides of a double helix of DNA to stay joined together?
The two sides of a double helix of DNA are held together by hydrogen bonds between complementary base pairs (adenine with thymine, and guanine with cytosine). These bonds form a stable structure that allows DNA to maintain its shape and function properly.
. How are complementary strands of DNA held together?
Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.
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 keeps DNA together?
DNA is held together by hydrogen bonds between the nitrogenous bases adenine (A) and thymine (T), as well as cytosine (C) and guanine (G). These base pairs form the rungs of the DNA double helix, providing stability to the overall DNA structure.
How are the two chains of a double helix held together?
The two chains of a DNA double helix are held together by hydrogen bonds between complementary base pairs. Adenine pairs with thymine, and cytosine pairs with guanine. These hydrogen bonds form the base pairs that hold the two strands of DNA together.
The two strands of a DNA molecule are held together by?
The two strands of a DNA molecule are held together by hydrogen bonds between complementary nitrogenous bases. Adenine pairs with thymine, and guanine pairs with cytosine. This base pairing allows the two strands to twist together in a double helix structure.
How are the two strands of the double helix held together?
The two strands of DNA double helix are held together by hydrogen bonds between complementary bases on opposing strands. Adenine pairs with thymine, and guanine pairs with cytosine. These base pairs create the rungs of the DNA ladder, stabilizing the overall structure of the double helix.
The DNA double helix looks like a twisted ladder What makes up each rung of the ladder What makes up the sides of the ladder What holds the rungs together at the sides?
Each rung of the DNA double helix is made up of a pair of nitrogenous bases (adenine-thymine or guanine-cytosine). The sides of the ladder are made up of alternating sugar (deoxyribose) and phosphate molecules. Hydrogen bonds hold the nitrogenous bases of the rungs together, creating the structure of the DNA double helix.
Did the Watson and Crick model of DNA say two strands of the helix were held together by covalent bonds?
Not covalent, hydrogen-bonds.
What make up both side of DNA double helix ladder?
The two sides of the DNA double helix ladder are made up of nucleotides. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). The nitrogenous bases on opposite strands pair together through hydrogen bonding (adenine with thymine, and guanine with cytosine), holding the two sides of the ladder together.
