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.
Transcription. Transcription, the first step in transforming DNA into proteins, is mediated by an enzyme named RNA polymerase. It consists of reading a sequence of DNA and transforming it, base by base, into a complementary sequence of RNA.ranscription, the first step in transforming DNA into proteins, is mediated by an enzyme named RNA polymerase.
