With more education and experience, accountants can become certified. Some financial documents, such as those submitted to the Securities and Exchange Commission, must be signed by a Certified Public Accountant.
Hyperchromicity is the increase of absorbance (optical density) of a material. The most famous example is the hyperchromicity of DNA that occurs when the DNA duplex is denatured. The UV absorption is increased when the two single DNA strands are being separated, either by heat or by addition of denaturant or by increasing the pH level.
Best Answer: Melting temp is when DNA strands separate, annealing temp is the temp where complimentary strands recombine (or anneal).The importance is this: In PCR, the temperature is cylced high to low, and a DNA polymerase that is heat-resistant is used so that it is not denatured at higher temps.f you don't reduce it to that lower temperature, the primers can never hydrogen bond with the DNA and cause extension. and this annealing temperature is CRUCIAL for the PCR to work.
