The two samples of `DNA,` `A` and `B` have melting tempreatures `(T_(m)) 340` and `350 K`,respectively. Can you draw any conclusion from this data regarding their base content?

Text Solution

Verified by Experts

The `B` sample of `DNA` having hegher `T_(m)` must be having more `GC` content as compared to sample`A`, since `GC` base pair having three hydrogen bonds (as compared to `AT` base pair having only two hydrogen bonds) results in stronger bonding.
