The main differences in the synthesis of purine and pyrimidine nucleotides -

  • The key difference between purine and pyrimidine synthesis is that purine synthesis occurs mainly via salvage pathway while pyrimidine synthesis occurs mainly via De novo pathway.
  • Purine and pyrimidine are nitrogen-containing bases.

What are 2 differences between purine and pyrimidine?

  • 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 uracil, are smaller and have a single ring, while the purines, adenine and guanine, are larger and have two rings.

What are the structural differences among purines and pyrimidines in DNA and RNA?

  • Purines and Pyrimidines are nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA.
  • The two-carbon nitrogen ring bases (adenine and guanine) are purines, while the one-carbon nitrogen ring bases (thymine and cytosine) are pyrimidines.
