Nucleotides are used for DNA and RNA. DNA is information needed so that they are able to align themselves. Also, this is what keeps all the organisms in your body to remain alive.
Cells
No, RNA nucleotides in transcription pair with complementary DNA nucleotides according to the base pairing rules (A-U, G-C), as opposed to replicating DNA in which DNA nucleotides pair with complementary DNA nucleotides (A-T, G-C).

Yes, nucleotides pair with specific complementary nucleotides based on their chemical properties.
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.
Nucleotides themselves do not store energy, but the bonds between nucleotides in molecules like ATP (adenosine triphosphate) can store and transfer energy within cells. ATP is known as the energy currency of cells and is used to power various cellular processes.
DNA polymerase can add free-floating nucleotides to the DNA after it has been "unzipped" by the helicase. It also checks for any awnsers.
The enzyme that matches RNA nucleotides to complementary DNA nucleotides is called reverse transcriptase. It is used by retroviruses like HIV to convert their RNA genome into DNA before integrating it into the host cell's genome.
Thymine is found on DNA nucleotides but not on RNA nucleotides. In RNA, thymine is replaced by uracil.
Purine nucleotides differ from pyrimidine nucleotides in their structure due to the number of nitrogen-containing rings they have. Purine nucleotides have a double-ring structure, while pyrimidine nucleotides have a single-ring structure.
