DNA Polymerases DNA Polymerases
DNA polymerase and RNA polymerase
Nitrogen bases in DNA
It is stored within the sequence of nitrogen bases.
an enzyme called DNA helicases unwinds the double helix before DNA replication begins. enzymes known as DNA polymerases move along each of tge DNA strands while adding nucleotides to the exposed nitrogen bases according to the base pairing rules.
All nucleotides are similar except for the nitrogen bases, which may either be adenine, cytosine, guanine, thymine, or uracil..
Purines and pyrimidines are nitrogen bases found in DNA and RNA .They are nitrogen containing heterocyclic compounds .Purines are large double ringed while pyrimidines are small single ringed .
DNA and RNA polymerase
The enzyme that adds nuclleotides to exposed nitrogen bases is DNA polymerase. This is how DNA can be replicated or repeated in the cell cycle.
Adenine, Guanine, Cytosine and Thymine
The four RNA nucleotides are named for their nitrogen bases. They are adenine, uracil, cytosine, and guanine.

All nucleotides are similar except for the nitrogen bases, which may either be adenine, cytosine, guanine, thymine, or uracil..
Nitrogen bases attach to deoxyribose sugar, in nucleotides.
