病毒核酸中的C、G含量有什么意义？

G+C含量，是病毒的分类依据之一。

它对病毒的作用没有么？比如它的生化特性等等，仅仅是作为分类依据?

病毒的生化特性多是由其基因组编码的蛋白决定的，例如对酸碱的稳定性、热敏感性、对有机溶剂的稳定性等等。未发现核酸组成和其生化特性相关的这样说法。如果你看到了类似观点，过来告诉我一声。

可以看看这篇文献：

I do not know much about virus... But generally speaking, the higher GC content, the more stable the DNA. If you look at thermostable becateria, the GC content is usually high (greater than 70 %!). This is because GC base pair shares three hydrogen bonding rather than two (AT).

yes,amberly.I have heard about this.My friend once told me.

CG含量对分类有指导意义的~
