Differbetween
The main difference between adenine and guanine is that adenine contains an amine group on C6, and an additional double bond between N1 and C6 in its pyrimidine ring whereas guanine contains an amine group on C2 and a carbonyl group on C6 in its pyrimidine ring.

What is the difference between adenine and thymine?
A. The purines, adenine and thymine, are smaller two-ringed bases, while the pyrimidines, cytosine and uracil, are larger and have a single ring. ... The pyrimidines, cytosine and thymine are smaller structures with a single ring, while the purines, adenine and guanine, are larger and have a two-ring structure.
What is difference between purine and pyrimidine?
They are nitrogenous bases that make up the two different nucleotides in DNA and RNA. Purines (adenine and guanine) are two-carbon nitrogen ring bases while pyrimidines (cytosine and thymine) are one-carbon nitrogen ring bases.
What is the relationship between guanine and adenine?
Each nucleotide base can hydrogen-bond with a specific partner base in a process known as complementary base pairing: Cytosine forms three hydrogen bonds with guanine, and adenine forms two hydrogen bonds with thymine. These hydrogen-bonded nitrogenous bases are often referred to as base pairs.
How do the two types of nitrogenous bases differ from each other?
The larger bases adenine and guanine are purines which differ in the kinds of atoms that are attached to their double ring. The other bases cytosine, uracil, and thymine are pyrimidines which differ in the atoms attached to their single ring.
What is the purpose of adenine?
Adenine is also used elsewhere in the cell, not just in DNA and RNA, but it's part of the molecule adenosine triphosphate, which is the energy source for the cell. So adenine plays a dual role in the cell: it's used for building DNA and RNA, but it's also used at storing energy in the cell.
Is adenine A sugar?
This nucleotide contains the five-carbon sugar deoxyribose (at center), a nucleobase called adenine (upper right), and one phosphate group (left).

What are DNA purines?
A purine is an aromatic heterocycle composed of carbon and nitrogen. Purines include adenine and guanine, which participate in DNA and RNA formation. Purines are also constituents of other important biomolecules, such as ATP, GTP, cyclic AMP, NADH, and coenzyme A.
What is a pyrimidine made of?
Pyrimidine is a simple aromatic ring composed of two nitrogen atoms and four carbon atoms, with hydrogen atoms attached to each carbon. The carbon and nitrogen atoms are connected via alternating double and single bonds. This bond structure allows for resonance, or aromaticity, causing the ring to be very stable.
Is guanine a purine?
Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)).
Why can a only pair with T?
The only pairs that can create hydrogen bonds in that space are adenine with thymine and cytosine with guanine. A and T form two hydrogen bonds while C and G form three. It's these hydrogen bonds that join the two strands and stabilize the molecule, which allows it to form the ladder-like double helix.
What is the definition of adenine?
(A-deh-neen) A chemical compound that is used to make one of the building blocks of DNA and RNA. It is also a part of many substances in the body that give energy to cells. Adenine is a type of purine. Enlarge.
What happens if adenine pairs with cytosine?
The bases of DNA can exist in rare tautomeric forms. The imino tautomer of adenine can pair with cytosine, eventually leading to a transition from A-T to G-C.
