    Satiability of DNA STRANDS when percentage of the nitrogen bases is given for example There are 2 strand of DNA named as strand 1 and strand 2. Strand 1 has 30% of AT and 70% of GC component while strand 2 has 45% of AT and 55% of GC component. Both strand are heated at 90 degree temperature. Which strand will be
