The biosynthesis of the DNA must consist in a replication or duplication. The study of the DNA structure as proposed by Crick and Watson (see fig. 6-15) gives an idea of the mechanism of this replication. Each nucleotide of the template DNA chain need only be recognized by a complementary nucleotide before the latter is […]

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”, from precursors like CO2, NH3, formiate, glycine etc., […]

In this article we will discuss about the fidelity of the replication of DNA. The DNA being the carrier of genetic information it is essential that this information remains correct. But the DNA can be damaged by the action of chemical or physical agents. The cell therefore possesses repair systems which can maintain the integrity […]
