Nitrogen bases in DNA
There are four nitrogen bases in DNA nucleotides: adenine (A), cytosine (C), guanine (G), and thymine (T). Each nucleotide contains one of these nitrogen bases.
It is stored within the sequence of nitrogen bases.
Nucleotides are broken down by the enzyme nucleotidase, which hydrolyzes nucleotides into their constituent components: nucleosides and phosphate groups. Subsequently, nucleosides can be further broken down by nucleoside phosphorylases and nucleoside hydrolases into nitrogenous bases and sugars. This process is essential for nucleotide recycling and cellular metabolism.
Adenine and Guanine are the two purines used as nitrogen bases in nucleotides. They form complementary base pairs with thymine and cytosine in DNA and with uracil and cytosine in RNA.
DNA and RNA polymerase
DNA polymerase is the enzyme responsible for adding nucleotides to exposed nitrogen bases during DNA replication. It catalyzes the formation of phosphodiester bonds between the incoming nucleotide and the growing DNA strand.
Adenine, Guanine, Cytosine and Thymine
The four RNA nucleotides are named for their nitrogen bases. They are adenine, uracil, cytosine, and guanine.
The enzyme responsible for adding complementary DNA bases to an exposed DNA strand is DNA polymerase.
The enzyme responsible for placing the corresponding nitrogen bases on the new strand of DNA is called DNA polymerase. DNA polymerase is essential for DNA replication as it helps add nucleotides to the growing DNA strand according to the sequence of the template strand.

There are four nitrogen bases in DNA nucleotides: adenine (A), cytosine (C), guanine (G), and thymine (T). Each nucleotide contains one of these nitrogen bases.
All nucleotides are similar except for the nitrogen bases, which may either be adenine, cytosine, guanine, thymine, or uracil..
It is stored within the sequence of nitrogen bases.
