populations are heterogeneous and dynamic buildings composed by ensembles of different genomes evolving in reaction to environmental alterations. 来自 Cambridge English Corpus For that reason, It could be useful for that virus to set the phase for every successive stage essential for viral
The framework on the DNA base guanosine as click here well as the antiviral drug acyclovir Antiviral medication are frequently nucleoside analogues (phony DNA developing-blocks), which viruses mistakenly incorporate into their genomes during replication.[a hundred and seventy] The lifetime-cycle with the virus is then halted since the newly synthesised DNA is inactive. This is because these analogues deficiency the hydroxyl teams, which, together with phosphorus atoms, website link with each other to form the potent "backbone" of the DNA molecule.
