What is the base of RNA in place of thymine which bonds with adenine?
The nitrogen base uracil takes the place of thymine in RNA. So in RNA, uracil pairs with adenine.
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).
In DNA, Adenine bonds with Thymine, Cytosine bonds with Guanine. In RNA, Thymine is replaced with Uracil (bases capitalized for easy emphasis/reference, not grammar.) Purines and Pyrimidines are two families of Nitrogenous bases. In DNA: Adenine and Guanine : Purines Cytosine and Thymine: Pyrimidines Adenine bonds with Thymine and Guanine bonds with Cytosine. A&T have 2 hydrogen bonds and G&C have 3 hydrogen bonds.
A nitrogen base is a nitrogen-containing molecule having the chemical properties of a base. The four nitrogen bases in DNA are adenine, guanine, cytosine, and thymine. Adenine pairs with thymine, and guanine pairs with cytosine. The four nitrogen bases in RNA are the same as DNA, except that the base uracil replaces thymine, and adenine pairs with uracil instead of thymine.
In DNA complementary base parings are the DNA monomers or bases, Thymine with Adenine (or Uracil and Adenine in RNA) and Guanine with Cytosine. Only these paring occur, the base thymine doesn't complement guanine or cytosine so doesn't pair with it. Thymine with Adenine forms 2 hydrogen bonds and Guanine with Cytosine forms 3 hydrogen bonds (these difference in the number of bonds formed is the reason for the complentary nature).
In RNA, there are four kinds of base: adenine, guanine, cytosine and uracil. There are no thymine bases. Therefore, there are no thymine and adenine base pairs. Addtional answer: The complimentary base of adenine in RNA is uracil which is a unmenthylated form of thymine. When menthylation occurs it becomes thymine which is paired with adenine in DNA. Thymine can also be called 5-methyluracil because it becomes thymine when methylation of uracil occurs at the…
In DNA replication, the nitrogen bases adenine and thymine, and guanine and cytosine form base pairs. The base-pairing rule states that in DNA adenine pairs with thymine and guanine pairs with cytosine, and in RNA adenine pairs with uracil. The paired nitrogen bases are held together with hydrogen bonds.
Adenine does form a base pair with thymine (linked with two hydrogen bonds). Cytosine does form a base pair with guanine (linked with three hydrogen bonds). Both the number of the bounds and the spatial location of these bonds ensure that the correct bases pair in the double string DNA. Nitpicking: Note that adenine can of course bind with all the bases (A,T,C,G) otherwise a DNA sequence like CAG would be impossible.
