How many hydrogen bonds link cytosine & guanine adenine and …

WebMay 14, 2024 · C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G) This is consistent with there not being enough space (20 Å) for two purines to fit within the helix and too much space for two pyrimidines to get close enough to each other to form hydrogen bonds between them. But why not A with C and G with T? WebAdenine (A) and guanine (G) are called purine bases as they have two carbon-nitrogen rings. On the other hand, cytosine (C) and thymine (T) are pyrimidines with a single carbon-nitrogen ring. As it has been established DNA has a uniform diameter, purines must always pair with pyrimidines. the orlen https://sundancelimited.com
