They are abbreviated by the first letter in their name, or G, A, T and C. The bases can be divided into two categories: Thymine and cytosine are called pyrimidines, and adenine and guanine are called purines. The DNA-repair enzyme O 6 -methylguanine-DNA methyltransferase (MGMT) acts to repair the altered guanine by removing the methyl group directly (Fig. The reason that guanine specifically pairs with cytosine (and not thymine, the other pyramidine) is a little more intricate. A Hoogsteen base pair is another alternate formation. Cytosine (Pyrimidine) and Guanine (Purine) can form three H-bonds and. The GU pairing, with two hydrogen bonds, does occur fairly often in RNA (see wobble base pair). A. Polar nature of C and A. What are their nitrogenous base of RNA and DNA?

When all of these come together they make a nucleotide, which are monomers or the basic unit of a Nucleic Acid. 9. The bases combine with the sugar to make the nucleotides adenosine, guanosine, cytidine, thymidine, and uridine. The other base pair in the DNA is A-T (adenine-thymine). This is a favourable situation for both molecules to be in, as both have 3 usable groups and no groups are in the way. What moral lesson you get from the legend of magat river? Guanine, an organic compound belonging to the purine group, a class of compounds with a characteristic two-ringed structure, composed of carbon and nitrogen atoms, and occurring free or combined in such diverse natural sources as guano (the accumulated excrement and dead bodies of birds, bats, and seals), sugar beets, yeast, and fish scales. It is possible however, for adenine to pair with cytosine, and guanine with thymine. There are, however, some alternate bond pairs which result from other hydrogen bonds. It's the G in the A, C, G, or T. Guanine in the double helix pairs with cytosine, so you will see CG pairs; one on one strand and one on the other. Why does cytosine make pair with guanine and not with adenine? What base does guanine pair with? And the CG pairs happen to bind more tightly than the AT pairs, so long stretches of CG make stronger helixes than stretches of AT.
