Final answer:
True. Denaturing involves breaking the hydrogen bonds between complementary bases, which separates the DNA strands into single strands. In the laboratory, DNA denaturation can be achieved by exposing the DNA strands to high temperatures or certain chemicals, causing the hydrogen bonds to break and the strands to separate.
Step-by-step explanation:
True. Denaturing involves breaking the hydrogen bonds between complementary bases, which separates the DNA strands into single strands. Hydrolysis, on the other hand, involves the breaking of DNA bonds in the backbone.
In the laboratory, DNA denaturation can be achieved by exposing the DNA strands to high temperatures or certain chemicals, causing the hydrogen bonds to break and the strands to separate. Reannealing or renaturing can occur when the temperature is cooled down or the chemicals are removed, allowing the DNA strands to come back together and reform the hydrogen bonds.
DNA denaturation and renaturation are important processes in biotechnology and the manipulation of DNA in the laboratory.
