How many hydrogen bonds do adenine and guanine have?
Uracil and Adenine do not form any bonds in making DNA.In DNA Adenine hydrogen bonds with Thymine (a double hydrogen bond). In RNA Uracil takes place of Thymine. Thus, Uracil and Adenine hydrogen bond in RNA. The base pairing is adjusted in RNA for this. Instead of A-T pairing that takes place in DNA, A-U pairing takes place in RNA.there are 2 hydrogen bonds between Adenine and Uracil (double bond).
How do the bases bond together a bonds with g bonds with?
A bonds with TG bonds with C
How much hydrogen bonds are in hf?
There are no hydrogen bonds in HF.
What is the weakest bond type?
It is not covalent, because it is the strongest type. The Correct answer is van der Waals.
What distinguishes hydrogen bonds from covalent bonds?
Hydrogen bonds are betweem molecules and are weak forces.
Why there are no hydrogen bonds present in RNA?
There are no hydrogen bonds present because RNA consists of a single stranded nucleotide chain.

Define complementary base pair?
Complementary base pairing is something seen in DNA and RNA molecules. This refers to which bases can form hydrogen bonds with each other when paired with a second strand of DNA or RNA. Adenine can only form hydrogen bonds with thymine and cytosine can only form hydrogen bonds with guanine. In RNA, uracil is used instead of thymine
What are thymine and adenine?
The nucleotides bind with 2 hydrogen-bonds
Are nitrogenous bases in RNA able to form hydrogen bonds with each other?
yes it can
The mRNA molecule is completed by the formation of what between the rna?
The mRNA molecule is completed by the formation of hydrogen bonds. These bonds are between the RNA nucleotides, which then separate from the DNA.
The rungs of the DNA lAdder are formed by pairs of substances called?
Nitrogen bases which are joined together by hydrogen bonds These bases are: Adenine (A) Guanine (G) Thymine (T) - replaced by uracil in RNA Cytosine (C) Uracil (U) - replaces thymine in RNA A = T there are 2 hydrogen bonds between A & T G ≡ C there are 3 hydrogen bonds between G & C
What is a basepair?
A basepair is a pair of nucleotides on opposite complementary DNA or RNA strands which are connected via hydrogen bonds.
What bonds hold RNA molecules together?
A hydrogen bond holds DNA together and a covalent holds rna together
How do the bases bond together a bonds with g bonds with?
A bonds with TG bonds with C
What is contained in nucleic acids?
Nucleic acids are polynucleotides. They are composed of nucleotides, which join together through phospho-diester bonds, with forms the sugar-phosphate backbone of the nucleic acid, and also through hydrogen bonds, between two complementary nitrogenous bases (in the case of DNA).The nucleotides which make up nucleic acids are composed of the following: a phosphate group (PO4), a deoxyribose sugar (in DNA) or a ribose sugar (in RNA) and finally a nitrogenous base. In DNA the purine nitrogenous bases are: adenine and guanine. The pyrimidine nitrogenous bases are: thymine (which bonds with two hydrogen bonds to adenine) and cytosine (which bonds with guanine through three hydrogen bonds. In RNA uracil replaces thymine and there are no hydrogen bonds between the nitrogenous bases as RNA is a single stranded molecule.
What structures is held together by hydrogen bonds?
Hydrogen bonds are strong intermolecular forces- weaker than covalent bonds that hold the molecules together. The diagram probaly shows molecules with otted lines from H atoms to an O or N aatom on an adjacent molecule.
