Complementary nitrogenous bases are held together by hydrogen bonds. Adenine pairs with thymine (or uracil in RNA) by forming two hydrogen bonds, while cytosine pairs with guanine by forming three hydrogen bonds. These hydrogen bonds provide the necessary stability for the base pairing in DNA and RNA molecules.

The two strands of DNA molecules are held together by?
hydrogen bonds between complementary nitrogenous bases.
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.
What type of bonding holds the two poly nucleotide strands of a DNA molecule together?
The two polynucleotide strands of a DNA molecule are held together by hydrogen bonds between complementary bases. Adenine pairs with thymine and guanine pairs with cytosine. This base-pairing contributes to the structural stability of the DNA molecule.
How are nucleic acids held together?
Nucleic acids are held together by phosphodiester bonds between the sugar and phosphate groups of adjacent nucleotides in the backbone of the molecule. Additionally, hydrogen bonds between nitrogenous bases in complementary strands help stabilize the double-stranded structure of DNA or RNA.
How are the two bases linked together in DNA?
Thymine and adenine! Also guanine and uracil.
The two strands of DNA molecules are held together by?
hydrogen bonds between complementary nitrogenous bases.
. How are complementary strands of DNA held together?
Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.
How are complementary of DNA held together?
Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.
What are the bondings is nitrogenous bases?
nitrogenous bases are held together with hydrogen bonds. adenine and thymine (or uracil) are held by 2 and guanine and cytosine are held by 3.
What type of bonds holds the bases together in pairs?
Hydrogen bonds hold the bases together in pairs in DNA. These bonds form between the nitrogenous bases adenine and thymine, and guanine and cytosine in a complementary manner, contributing to the overall stability and structure of the DNA molecule.
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.
What type of bonding holds the two poly nucleotide strands of a DNA molecule together?
The two polynucleotide strands of a DNA molecule are held together by hydrogen bonds between complementary bases. Adenine pairs with thymine and guanine pairs with cytosine. This base-pairing contributes to the structural stability of the DNA molecule.
How are the bases held together in a double helix?
Nitrogenous bases.That would be hydrogen bonds.
What type of molecules are bonded together by hydrogen bonds in DNA?
Nitrogenous bases are held together by hydrogen bonds, thus making them easier to separate during DNA replication.
What is the most basic DNA structure?
The most basic DNA structure is a double helix composed of two complementary strands of nucleotides held together by hydrogen bonds. Each strand consists of a sugar-phosphate backbone with nitrogenous bases (adenine, thymine, cytosine, and guanine) attached to the sugars.
Which bases are complementary to one another how are they held together in the double helix of DNA?
In DNA, adenine pairs with thymine and guanine pairs with cytosine, forming complementary base pairs. These pairs are held together by hydrogen bonds, with A-T forming two hydrogen bonds and G-C forming three hydrogen bonds. This complementary base pairing is essential for the stability and replication of the DNA molecule.
Which type of chemical bonding holds the two strands of DNA together in the double helix?
When two strands of DNA that have exactly complementary base pairing (Adenine bonds with only Thymine, and Cytosine with Guanine) the base forms a hydrogen bond to the base on the opposite strand, only if the base pairing is complementary. So, in short the double helix form is held together by hydrogen bonds between the bases present on the strand. This means as the two strands are split apart, a new complimentary strand is formed against each, resulting in two identical double helices where there was just one before. It is by this means that the instructions for the code of life are copied and passed on.
