Best Answer

In reference to the melting of DNA: as DNA melts (denatures from a double-stranded molecule to two single strands) the UV absorbance INCREASES. This absorbance increase is referred to as a "hyperchromic shift" or the hyperchromic effect. Thinking about this situation in reverse: the UV absorbance DECREASES as two DNA strands anneal to form double stranded DNA. This is referred to as the "hypochromic effect".

(Please note, there is an answer on answers.com that incorrectly states the opposite, that absorbance decreases with melting. This is incorrect. Two single strands of DNA have higher absorbance than the double-stranded molecule.)

What is normochromic cells?

* Cell color (blood cells): (generally refers to the staining characteristics which reflects the hemoglobin concentration. Terms that describe hemoglobin content end with "chromic".) ~ normochromic (sufficient or normal amounts of hemoglobin) ~ hyperchromic (containing an unusually high concentration of hemoglobin in its cytoplasm) ~ hypochromic (containing an abnormally low concentration of hemoglobin)

What is hypochromic microcytes?

Microcytic hypochromic anemia is a condition where the red blood cell count and hemoglobin levels are low (hence anemia), with small red blood cells (microcytic), and red blood cells that stain less intensely than normal (hypochromic). The most common cause is iron deficiency. Low levels of iron in the body.


What are the health implications of hypochromic anemia?

Hyperchromic anemia can cause a lower red blood cell count and higher levels of hemoglobin in the red blood cells. Other effects include brittle nails, sore mouth, headaches, and shortness of breath.
