∙ 15y agoIn DNA, A (adenine) is paired (by hydrogen bonding) with T (thymine).
In RNA, there is no T, and A pairs with U (uracil).
G (guanine) pairs with C (cytosine) in both DNA and RNA.

What type of bonds hold the individual DNA bases together?
If the DNA nitrogenous bases (A&T, G&C) alone, its the Hydrogen bond. Phosphate-Sugar= phosphoester bond Sugar-Nitrogenous bases= Beta N-glycosidic bond Sugar-phosphate-sugar = phosphodiester bond
How are the two bases linked together in DNA?
Thymine and adenine! Also guanine and uracil.
How many hydrogen bonds are formed between C and G?
They are made of triple bonds. (3)
What nucleotides bond?
In DNA, there are four types of nucleotides. These are Guanine, Cytosine, Thymine and Adenine. Guanine and Adenine are purines whereas Cytosine and Thymine are pyrimidines. Adenine will always bond with thymine in DNA. Therefore, guanine and cytosine bond together. These comnplementary base pairing allows the DNA to be replicated and is also used in protein synthesis.
Is there double and triple bonds present in DNA?
DNA is made up of double and triple bonds. If you remember the nitrogenous basis i.e. adenine. guanine, cytosine and thymine, where adenine pairs with thymine by double bond and guanine pairs with cytosine with triple bonds.
How do the bases bond together?
A bonds with TG bonds with CT bonds with AC bonds with G
How the bases bond together?
A bonds with TG bonds with CT bonds with AC bonds with G
What type of bonds hold the individual DNA bases together?
If the DNA nitrogenous bases (A&T, G&C) alone, its the Hydrogen bond. Phosphate-Sugar= phosphoester bond Sugar-Nitrogenous bases= Beta N-glycosidic bond Sugar-phosphate-sugar = phosphodiester bond
How are the nitrogen bases held together in the center of the DNA molecule?
The nitrogen bases bond A-T and C-G via hydrogen bonds. The bases are held together in the string by a backbone of alternating phosphate and sugar molecules.
What are the pairing rules of DNA?
A=Adenine T=Thymine G=Guanine C=Cytosine A and T bond together with 2 hydrogen bonds G and C bond together with 3 hydrogen bonds A T G | C
What type of bond holds together the base pairs in a DNA helix?
Hydrogen Bonds are the bonds that hold the complimentary bases together. G to C and A to T. However the bonds that hold the nucleotides together on each side of the double helix are called Phosphodiester bonds or linkages.
What bond holds the bases together in a DNA molecule?
Base pairs in DNA are attached to each other via hydrogen bonds. The base pairs are attached to the backbone by covalent bonds.
How do bases bond together?
Note that adenine only bonds with thymine, and cytosine only bonds with guanine. The nitrogen bases are held together by hydrogen bonds: adenine and thymine form two hydrogen bonds; cytosine and guanine form three hydrogen bonds.
What type of bonds form between the nitrogenous bases of a DNA molecule?
A hydrogen bond--two between A and T and three between G and C.
Paired bases are held together by weak bonds called?
Hydrogen bonds
The bases of the two DNA chains are linked in the middle of molecules by?
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 are the mRNA's C and G held together by?
mRNA is single stranded - meaning the bases are not found in pairs (AT, GC) like they are in a double-stranded structure. Therefore the bases themselves will not be directly linked, but the entire nucleotide (sugar, phosphate and base) will be linked to the previous and next nucleotide in the chain by a phosphodiester bond. In DNA (or dsRNA) the C and G are held together by three hydrogen bonds.
