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.
Definition [edit]. Difference in absorbance of ultraviolet light between single stranded and double stranded DNA. Hypochromicity describes a materialâs decreasing ability to absorb light. Hyperchromicity is the materialâs increasing ability to absorb light.The Hypochromic Effect describes the decrease in the absorbance of ultraviolet light in a double stranded DNA compared to its single stranded counterpart.efinition [edit].
