Biosynthesis of ribonucleotides
WebMost organisms can synthesize the purine and pyrimidine nucleotides that serve as the building blocks of RNA (containing nucleotides in which the pentose sugar is ribose, called ribonucleotides) and DNA (containing … WebADVERTISEMENTS: In this article we will discuss about the process of biosynthesis of nucleic acids. Biosynthesis of Nucleosides-5′-Triphosphates: Among animals, some amino acids cannot be synthesized and must therefore be supplied through diet (essential amino acids). On the contrary, purine and pyrimidine nucleotides can be synthesized “de novo”, …
