Guanine and adenine
4 nucleotides (:
A codon is a group of nucleotides that are placed beside each other. A codon has three nucleotides and it specifies a single protein.
Three nucleotides make up a gene.
Pyrimidines are nucleotides that have a single ring as their nitrogen base. The two pyrimidines are Cytosine and Thymine.
bases found in nucleotides :)
The five nucleotides are adenine and guanine(purines), cytosine and thymine(pyrimidines), and uracil (which replaces thymine in RNA).
cytosine and guanine
The purine are: Adenine and Guanine The pyrimidines are : Cytosine and uracil
purines, pyrimidines, nucleotides and nitrogen bases.
It would look like a zig zag because purines are bigger than pyrimidines
DNA contains nitrogenous base pairs (purines and pyrimidines), along with deoxyribose sugar, nucleosides and nucleotides.
DNA contains four nucleotide bases, which are adenine, thymine, cytosine and guanine. The pairs of nucleotides that can be held together by weak hydrogen bonds are purines and pyrimidines.
Purines bond to pyrimidines
During the bonding of two nucleotides hydrogen bonds are use and adenine and thymine bind together. It also causes purines to bind with pyrimidines, and double ring nitrogenous bases connect to single ring bases.
Adenine and Guanine are just purines (the other nucleotides are pyrimidines), and these have one 6-parts ring with 3-parts ring attached.
