Complementary bases in DNA are held together via hydrogen bonds. Between G and C there are three hydrogen bonds and between A and T there are two hydrogen bonds.
What else can I help you with?
What is the definition of DNA molecule?
Consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine
Each DNA strand has a backbone that consists of alternating?
sugar-phosphate groups. These groups are linked together by phosphodiester bonds, forming the DNA backbone. The nitrogenous bases are attached to the sugar molecules extending from the backbone.
What are the two bases that are linked by an H bond in RNA?
adenine and uracil and cytosine and guanine?
Are nitrogen bases molecules?
yes it is
Bases of DNA are linked together by intermolecular forces are called?
The two strands of DNA are linked together by hydrogen bonds which occur between the nitrogen bases opposite one another along the molecule.
How are the four bases of DNA linked?
Bases in DNA are linked through hydrogen bonds. There are two hydrogen bonds between Adenine and Thymine There are three hydrogen bonds between Guanine and Cytosine
What does the number of T nitrogen bases in DNA molecules equals the number of what?
A molecules
The number of T nitrogen bases in DNA molecules equals the number of?
A nitrogen bases
What are the two main sections of the DNA molecule?
The two main sections of the DNA molecule are the sugar-phosphate backbone and the nitrogenous bases. The sugar-phosphate backbone consists of alternating sugar and phosphate molecules that form the structural backbone of the DNA molecule. The nitrogenous bases (adenine, thymine, cytosine, and guanine) are connected to the sugar molecules and form the internal structure of the DNA molecule through complementary base pairing.
What molecules make up the the sides of a DNA molecule?
The sides of a DNA molecule are made up of alternating deoxyribose sugar and phosphate molecules, linked together by phosphodiester bonds. This forms the backbone of the DNA double helix, with the nitrogenous bases projecting inward towards each other.
What bases are not found in RNA molecules?
RNA has the bases A, C, G, and U. It does NOT have the base T.
What element are molecules basic on?
Bases have the group OH-.
