DNA shows hyperchromicity on: |
| A. | heating |
| B. | cooling |
| C. | crystallizing |
| D. | replication |
| Answer» A. heating | |
|
Explanation: When a DNA solution is heated enough, the double-stranded DNA unwinds, and the Hydrogen bonds that hold the two strands together weaken and finally break. The process of breaking a double-stranded DNA into single strands is known as DNA denaturation, or DNA melting. The hyperchromicity of DNA occurs when the DNA duplex is denatured. |
