in order to determine the rate of dna synthesis in mammalian tissue administration of which of the following labeled substance would be specific in labelling dna?
a)adenosine
b)cytosine
c)thymidine

i would appreciate the ans with expl.

C. thymidine.

Remember in DNA , 4 bases are ATCG
in RNA, 4 bases are AUCG,

So T is unique in DNA. But not ACG.

yeah thats totally true...
that way you differentiate RNA bases from DNA's,..
